SparkFun Pro Micro - RP2350 _RPI_Proto_HATs 96" mini OLED display connects

96" mini OLED display connects with the board over an I²C interface

The WiFi section on this board is based on the Espressif ESP8285 chip which is an ESP8266 with 1MByte FLASH memory integrated onto the chip making it a complete WiFi-only board requiring very few external components

We've also updated this PCB with Adafruit Pinguin to make a lovely and legible silkscreen

the different conduction levels of the phototransistor when it passes over black and white lines can generate different output voltages

SparkFun Pro Micro - RP2350 _RPI_Proto_HATs 96" mini OLED display connectsThe SparkFun RP2350 Pro Micro provides a powerful development platform in SparkFun's compact Pro Micro form factor, built around the RP2350 from the Raspberry Pi Foundation. This board uses the updated Pro Micro form factor. It includes a USB C connector, Qwiic connector, WS2812B addressable RGB LED, Boot and Reset buttons, resettable PTC fuse, and PTH and castellated solder pads. The RP3250 is a unique dual core microcontroller with two ARM Cortex
