Radxy, the company behind the Rock Pi 4 is back! A couple of days ago, I've received the Rock Pi S (see Fig. 1), a miniature developer board that measures just 38 x 38 mm. The board is powered by the Rockchip RK3308 SoC, which integrates four 64-bit ARM Cortex-A35 cores (Ultra-High-Efficiency). Each of the cores reaches up to 1.3 GHz. The SoC also has a built-in voice activity detector (VAD) for use with IoT and smart voice applications.
Despite its tiny size, the Rock Pi S includes a 26-pin GPIO header along with a 26-pin audio/voice header and a microSD card reader. Additionally, the Rock P...

You get a very good price for $144.99 at Banggood for the bigger 47 mm version in the International Version. This supports English and Chinese language. The price is valid for the 47mm variation (42mm variants are currently not available) and will be adjusted as soon as you put the watch into the shopping cart (see figure at the end).

Timeular is still on Summer Sale with up to 50% discount! Limited stock left, don’t miss out!
First of all, this article is a product review which was/is not supported by Timeular GmbH or similar. I bought the product two weeks ago, because I wanted to test it. I missed out the Kickstarter campaign (2016) and the regular price for the octahedron was too expensive for me.

I've been very busy the last weeks. I moved to a new apartment and I was living between moving boxes. Four days ago, I managed to put my desk together and now I have some time (not a lot) to write a new article.
Last month I've received from GearBest two Aqara sensors:
These sensors use Zigbee and I connected them to a Raspberry Pi running Raspbian OS and a dockerized version of Home Assistant (DIY tutorial). This connection was made without using any Xiaomi gateway (DIY tutorial).

This week, I received from Seeed Studio a MAiX Dock to review it. The main board of the kit includes a Sipeed M1w which is a compact module like the ESP32 but based on the Kendryte K210 dual core RISC-V processor. It is designed for low power artificial intelligence workloads, such as face detection, object recognition, or audio processing. There are two type of modules: the Sipeed M1 and M1w, the last one includes WIFI connectivity.
The main features of the MAiX Dock boards are:
- Display I/F – An FPC24P socket for 8-bit MCU LCD
- Camera I/F- An FPC24P socket for DVP camera
- Storage – micro SD s...
This month, I received the M5Stack FIRE development kit with a PLC base kit from Banggood to review (see Fig. 1). After using it, I can affirm that the M5Stack takes an alternative approach to ESP32 prototyping, because the resulting projects are almost simultaneously finished products. This is possible because the board is housed in a stylish and robust hosing with graphics display, buttons, microSD card slot, USB-C port and speakers. I tested the M5Stack FIRE development kit, and the board includes also a MPU6050, MAG63110 (MPU9250 on the new versions), BSE3729 and a PSRAM to extend the ESP3...
