Artpi-based Gizwits Cloud expansion board

Overview

1. Extended version hardware resources

1. ESP8266 (including download circuit) 2. RGB colored lights 3. SHT30 temperature and humidity sensor 4. bmp280 air pressure sensor 5. OLED screen displays sensor data

2. Design ideas

Since Artpi's onboard wifi module is not friendly to novices, we chose the commonly used ESP8266 for wifi connection. By flashing Gizwits firmware development, we can view sensor data, control lights on and off and other functions on our mobile phones. SHT30 can detect temperature and humidity, bmp280 can detect atmospheric pressure, and the OLED screen displays the data for easy local viewing.

3. Precautions

ESP8266 needs to download firmware for better development, so the download circuit of ESP8266 will be onboard, and a jumper cap will be used to switch the connection with the microcontroller.

MSP430 FRAM Quality and Reliability
A single FRAM cell can be viewed as a dipole capacitor consisting of a thin film of ferroelectric material (a ferroelectric crystal) between two electrode plates. This crystal structure consists of a
There is a problem in using tlv5616, it's very strange
There is a problem when using tlv5616. No matter how I write the program, the same program needs to be repeated twice before it can be updated? Why? Has anyone encountered this? Has anyone used this c
The first time I drew a board, I couldn't burn the program into the JTAG after it was made. I cried
This is the schematic diagram for JTAG, completely copied from TI... This is my crystal oscillator. I didn't know it at the time... I also put the crystal oscillator on the opposite side, and the SPI
