January 4, 2024Hardware,LuckFox128MB,ARMv7,BusyBox,Ethernet,LuckFox Pico Pro,RNDIS I’ve been diving down multiple rabbit holes recently with Linux onreallytiny SBCs. Nope, not the Raspberry Pi, but things that are roughly a quarter of the size and just one-quarter of the price, too....
There's #1109 open for the original T5-4.7 module. This year the vendor introduced a new version of the module, which they call "T5 4.7 Inch E-paper V2.3" or "T5-4.7 Plus". The vendor advertises the new ESP32-S3 chip and TF-card reader a...
Therefore these phases need a quarter the clock cycles compared to standard SPI. In terms of performance: QIO > QOUT >> DIO > DOUT. QOUT or QIO are much faster than DIO or DOUT. ESP Easy official builds uses DIO for everything except DOUT for the smaller (1M size) units. ...

ESP32-Touch, Hall, I2C, PWM, ADC, & DAC: The ESP32s, are a series of inexpensive microcontrollers introduced in the last quarter of 2016. They are powerful systems on a chip (SoC), they replace the ESP8266, and perhaps one might even say the Arduino UNO.
