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.
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
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
an SMD module (sadly not OSHW), featuring an nRF52833, an MPP converter, and FRAM in the form of a MSP430FR5962, a low-power programmable RTC and generally low board voltage (2V)
a board that adds a CMSIS-DAP debugger and pin headers
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
