SparkFun Pro Micro - RP2350 _RPI_Proto_HATs 7MΩ resistor

7MΩ resistor

7V Detecting the particle diameter >1μm Dimensions 59(W) × 45(H) × 22(D) mm Humidity Range 95% rh or less Notes:

allows signal isolation

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

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

SparkFun Pro Micro - RP2350 _RPI_Proto_HATs 7MΩ resistorThe 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
