LoDev S76S. Its based on AcSIP LoRaWAN module S76S . AcSIP seems to have good inventory even in these times of silicon shortage. Once ported, maybe a good option for LoRaWAN prototyping.
yes the adafruit rp2040 would be my favourite target - with a plug-in transceiver thats already supported
There are more RISC-V boards available:
Mouser, 6.78 €
AliExpress, $26
So very confusing for espressif to create a RISC-V system with the name “ESP32”! (But at that price… wow)
The Hi3861 is now also available on the cheaper HarmonyOS development for $11.
But there are also new chips: QinHeng Electronics replaced the Cortex-M0 on their designs with a RISC-V CPU to create e.g. the CH573 MCU:
It’s a very low-end chip, but comes with BLE 4.2 and USB. There is a dev board available:
AliExpress 17€
This is a neat little board with an ESP32C3, which is the new RISC-V based member of the ESP32 family
m5stack $6

ST released their new line of ultra-low power MCUs accompanied by the usual dev boards like the NUCLEO-U575ZI-Q.
Mouser 20€
You can now buy boards with the BL702 (RISC-V, 802.15.4 radio) based on the XT-ZB1 module:
AliExpress 2€
There is an SDK with an IEEE 802.15.4 example, the radio driver appears to be a blob though
sipeed released a micro sized board off the BL702 chip… apparently they are developing their own env… so that now the wireless drivers and blob should now be accessible? https://twitter.com/SipeedIO/status/1598121931798376450
Hi there!
I found a cheap chinese MCU board with WiFi+Bluetooth support:
MicroWinner W801. Based on C-SKY architecture. 2.5$ Aliexpress.com
SDK with examples: github
Chinese RM is difficult to read but the board has many features for RIOT. Also exists W806 version without wireless interfaces and W800 - only chip in QFN32 with WIFI+BLE.
Would it be an idea to put all these suggested boards in a Google Spreadsheet where their implementation (or availability) status can be tracked?
Because some of the earlier suggested boards in this thread are now already economically deprecated, because their prices have skyrocketted during the chip-crisis. I don’t think it’s worthwhile to still create implementations for those. On the other hand, others still are relevant and it’d be useful to have a clear overview of the progress of each one.
The Riotee boards look nice, not only due to their name: these’d be great for showing off how we’re energy efficient with ztimer now.
They consist of
Hi, Google had annonced a brand new MCU board for AI@Extreme Edge : The Google Coral Dev Board Micro is a microcontroller board with a dual-core MCU (NXP i.MX RT1176 (Cortex-M7 and Cortex-M4)), Coral Edge TPU (4 TFlops INT8 for 2W), a Himax HM01B0 CMOS color camera (324 x 324 px or QVGA (320 x 240 px); 110º diagonal FOV; ƒ/2.0 focal ratio; Fixed focus), a PDM microphone, user and reset buttons, four LEDs and 2 GPIO headers with 12 pins (digital, analog, and power pins). OS is FreeRTOS. It provides TensorFlow Lite for Microcontrollers to execute ML and DL models on either the MCU or with acceleration on the Edge TPU
The CH32V208 is a 144 Mhz RISC-V BLE (5.3) MCU for 1.0 USD (1k units) to 1.5 USD
Evaluation boards can be bought for around 10 USD on Aliexpress.
SDK is available on Github. Apparently with integrations into FreeRTOS and Harmony OS.
Documents and specs are available on their website.
