SiPeed AI at the Edge



Edge AI looks like going to be the next big things. In this blog post, I am going to introduce a very cheap and yet power AI chip based on Kendryte K210. K210 is based on open source RISC-V instructions set. According to WikipediaRISC-V started in 2010 and in the recent 2 years, actual chips are produced with prototyping boards.

A few China companies have started to build prototyping kits around this chip. One of these company is SiPeed. They have produced a few form factors of prototyping board and I have gotten hold of the Maixpy GO board.
The Maixpy Go has the following features:

  • 2.8 inch touch LCD
  • Camera
  • TF card slot
  • Mic
  • RGB LED
  • Speaker
  • WIFI
  • Rechargeable battery
  • Powered via USB C. The USB-C also act as Uart for transferring of codes and flashing of firmware.
There are a few ways to program the kit, micropython, Arduino IDE or Platform IO. For micropython, there is Maixpy IDE which is a port of OpenMV IDE.

Sipeed also has 2 interesting peripherals, microphone array and binocular camera. The subsequent post I will write more about the 2 peripherals.

Looks like this is going to be a very interesting AI and IoT platform. I will follow-up with more write-up especially the AI portion. Stay tune!

Update: Transfer Learning using mobilenetv1 in colab to generate kmodel file.

Using ESP-Link transparent bridge (ESP-01 and Arduino Pro Mini)

Recently stumbled across an interesting open source project ESP-Link. Its main purpose is to network-enable a non-network microcontroller (MCU) such as Arduino Uno, Pro mini or Nano using ESP8266. The author termed it as "Transparent Bridge". The ESP and MCU  communicate via the serial link and there is a companion Arduino library EL-Client for the MCU to connect up the network using MQTT, REST, TCP and UDP.
Setup I have put together an ESP-01 and an Arduino Pro Mini for this experiment. I have chosen a 3.3 version Pro mini so that I do not need to do any voltage level shifting between the I/O pins. In order to have a stable voltage source, the ESP8266 is powered by Pro Mini and the Pro Mini "RAW" pin is connected to a 5v USB power source. The RAW pin can take voltage up to 12V. The reset pin of Pro Mini is connected to GPIO 0 of ESP-01. This enables the ESP-01 to reset the Pro Mini.




I have linked up an APDS 9960 sensor to it and periodically send the luminosity a…

DIY Sonoff RF Bridge

Tasmota recently supported the RF bridge by iTead which allowed for RF 433 remote devices to be controlled/controlling using Sonoff products. e.g A handphone can be used to control a remote RF device or an RF remote control can use to control a WIFI enabled device.

By using Tasmota, I can control the device using MQTT. This idea fits exactly to my smart home plan. Here is the schematic:



I cheated a bit by having ESP01 mounted on a breakout board. This breakout board converts all the external pins to 5v which simplified the wiring and I do not need to use a voltage level shifter. Moreover, the Arduino 3.3v power does not have enough current to power the ESP reliably and I have to power it via the 5V from Arduino Uno. Next, I used an Arduino Uno prototype shield with a tiny breadboard to hold all the components together. For the RF 433 transmitter/receiver, I am using the development kits when I purchased the all-in-one Arduino development kits. An antenna is added for more sensitivity.
