I'm using this for an SDR project. It's perfectly capable of running gqrx and moderately complex GNURadio flows, and with a little tweaking can handle SDRTrunk P25 decoding, using an RTLSDR or even a hackrf at 10 Msps. It's typically compared to Raspberry Pi 4 and some of the ODROID boards, but this one sort of defines its own class. It's perhaps less "user-friendly" than the RPi, but as with most things in this world, if you want to live on the bleeding edge, you have to work for it. The board is based on the Amlogic A311D, an ARM64 SOC intended for TV boxes. Its architecture features four high-performance cores and two power-efficient cores. This arrangement is perhaps better than the more common arrangement of many little cores and few big ones (or equal numbers), as it lets you have your device always active handling background tasks with minimal power drain, and summon massive power on demand. There's also a suspend-to-RAM mode that drops power consumption to near zero, with several wakeup options available. Out of the box, you can power it up and it'll boot a perfectly usable version of Android from eMMC. Or you can put a Linux image on an SD card and boot that, then install it to the eMMC, or not. They've engineered this to be fairly difficult to hard-brick, it has a ROM loader that can be summoned by pushing buttons at power-on, and Khadas provides a "rescue" SD image that can fix the bootloader, backup/restore/erase/upgrade the eMMC, etc. On the Linux side, it can be a little rough around the edges, but there's a very active team of open source developers supporting it, and it's possible to run latest or nearly-latest Linux kernels on it. Khadas has active forums on their site where you can get support from the devs and other users. Best features: Low (!) power draw: With the ondemand CPU governor, and without making any special efforts like disabling cores, this thing idles around 2.2W, connected to 5GHz WiFi and Bluetooth, and sitting at the GNOME desktop. Power usage can be dropped even lower by tweaking CPU governor settings, disabling cores, disabling WiFi/BT, putting the HDMI to sleep, etc. I've seen it idle down around 1.3W, but with most of the goodies turned off. On the other end of the spectrum, it can surge over 10W under heavy load, and deliver the sort of performance you'd expect from an ARM at that wattage. Onboard power regulator: You provide a fairly clean source of 5-20VDC, it takes care of itself. If you're on the lower end of that range, you have to allow for brief spikes of high current, which is why they recommend a 4A adapter. You can use a USB-C Power Delivery adapter, the VIM3 will request what it wants, or you can provide suitable voltage through the USB port or through the header behind it. If powering externally from more than 5V, do NOT plug your computer or anything else you want to keep into the USB-C port, the power rails are common. The two USB-A ports provide regulated 5V regardless of supply voltage, and with a little poking around in the kernel device trees, you can even turn the power to them on and off under software control. Power & reset buttons, and a Function button that's used at bootup to enter recovery mode, and also can be read in software. There's an onboard IR receiver too, for use with Khadas's remote, or other ones with a bit of hacking. USB in abundance: The two Type-A connectors are standard USB. One is USB2, the other is USB3 (unless you enable the PCIe port, then it falls back to USB2). The Type-C carries a USB2 OTG port, and there are two others available with a little work: one hiding on the PCIe/M2 connector (?) and one on the GPIO connector. That PCIe/M2 port: You can turn that on instead of USB3, and use a pretty good variety of one-lane M2 PCIe cards or SSDs (not SATA ones though!). Support for most of the basic functionality is in the mainline Linux kernel, and the open-source dev team provide a bunch of patches to add more. The vendor provided kernel-4.9 based Ubuntu image is a bit long in the tooth, but does work fairly well and has support for all the bells and whistles. And... Full schematics and IC datasheets on Khadas web site. If you want to know how something works, how you can hack it to do something else, or what its voltage limits are, it's there. And the website and forums are full of useful info on how to use most of the board's features. Some caveats: You need a heatsink. The Khadas passive one is fine for light load and engineered to fit nicely without bulking up a very slim board. If you're going to run sustained heavy load you need more, or you'll hit thermal throttling and core shutdowns. Khadas has a heatsink-with-fan option, or you can roll your own, and there's a PCB header for a PWM variable fan. The white "heartbeat" LED speeds up as temps rise, a nice touch. Clean power is a must, especially if you're using 5V since there's very little headroom for the regulators to work with. The RMS current is quite low, but it can surge over 10W under load. If your VIM3 appears to be booting but has no video, check your power first, the HDMI really doesn't like power sags. Some of the I/O pins are 3.3V and some are 1.8V, and the docs aren't super clear on which. The schematic appears to be the ultimate authority on this matter. The forums are helpful too. Some of the advanced stuff (notably the NPU) doesn't work well (or at all) with the closer-to-mainline Linux kernels, you need to use the vendor-provided 4.9 kernel or do a lot of hacking to get it going. I didn't try out the NPU, since I don't need it for my project. The vendor 4.9 kernel didn't support my (third party) touchscreen for some weird reason, but the newer 5.12 does, so I didn't put a lot of effort into figuring out why. Overall, I'm duly impressed with this board, will probably buy another to experiment with after I finish my project (I kind of want to see that NPU do something), and will be keeping an eye out for new products from Khadas. Review: The board doesn't boot at all. ## Features - High Performance: Amlogic A311D - x4 2.2Ghz Cortex A73, x2 1.8Ghz Cortex A53 12nm SoC fabrication process for low heat 2T2R AC Wi-Fi with RSDB Features Bluetooth 5.0 USB 3.0 Available Gigabit Ethernet with WOL support LPDDR4/X USB-C PD for heavy applications - Neural Network Accelerator: NPU: Supports a maximum frequency of 800MHz at 5.0 TOPS INT8 inference up to 1536 MAC Internal L2 cache (512KB) and system workspace buffer (1MB) Supports all major deep learning frameworks including TensorFlow and Caffe - Maker Friendly: Stackable Design Programmable MCU 3 Programmable LEDs (Blue, Red and White) XPWR for external Power button Onboard SPI Flash Khadas TST Khadas KBI - Business Applications Dual independent displays with GSensor H.264 / H.265 Encoding Supports multi-video decoding up to 4Kx2K@60fps+1x1080P@60fps VIN Power Input - Rich IO: 40 Pin GPIO Header (USB, I2C, I2S, UART, ADC etc) 8-ch I2S for Microphone Array application (over M.2 Connector) MIPI-DSI MIPI-CSI Designed with GPIO Extender Chip ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07WD6CL7Y | | Best Sellers Rank | #143,385 in Computers ( See Top 100 in Computers ) #1,611 in Motherboards | | Brand | khadas | | Built-In Media | VIM3 Basic | | CPU Model | A-Series Quad-Core A6 | | Compatible Devices | Monitors, Touchscreens, Microphones, Speakers, Cameras, GPIO-compatible devices, M.2 cards, and other devices with compatible interfaces | | Connectivity Technology | Wi-Fi, LAN, Bluetooth | | Customer Reviews | 4.2 4.2 out of 5 stars (56) | | Manufacturer | khadas | | Memory Storage Capacity | 16 GB | | Mfr Part Number | KVIM3-B-004 | | Model Name | VIM3 | | Model Number | AP6356S | | Operating System | Linux | | Processor Brand | ARM | | Processor Count | 8 | | Processor Speed | 1.8 GHz | | RAM Memory Installed | 2 GB | | RAM Memory Technology | LPDDR4 | | Total Usb Ports | 4 | | UPC | 724873165269 | | Wireless Compability | Bluetooth | ## Product Details - **Brand:** khadas - **CPU model:** A-Series Quad-Core A6 - **Installed RAM memory size:** 2 GB - **Memory storage capacity:** 16 GB - **Model name:** VIM3 ## Images ![Khadas Single Board Computer, VIM3 Basic Amlogic A311D,Faster CPU,Neural Processing Unit for A.I.Switchable PCIe and USB 3.0,Dual Independent Displays,Dual Cameras(2+16GB) - Image 1](https://m.media-amazon.com/images/I/91mmMuuPhAL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by V***D on 23 June 2021* This is a very powerful and energy-efficient SBC, with features that well justify the premium price.

But the board itself worked great right out of the box and passed all other tests. Just need to write code for the interface to app configuration. ## Frequently Bought Together - Khadas Single Board Computer, VIM3 Basic Amlogic A311D,Faster CPU,Neural Processing Unit for A.I.Switchable PCIe and USB 3.0,Dual Independent Displays,Dual Cameras(2+16GB) - Khadas Passive Vim Heatsink for Single Board Computer of VIM1 /VIM2 /VIM3 /VIM3L/ Edge-V/DIY Case - Khadas 4G LTE Module for VIM3/3L, Compatible with New M2X Extension and M2X Extension Boards --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.br/products/282208283-khadas-single-board-computer-vim3-basic-amlogic-a311d-faster-cpu](https://www.desertcart.com.br/products/282208283-khadas-single-board-computer-vim3-basic-amlogic-a311d-faster-cpu) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-05-22*
