5893 for Adafruit High Voltage UPDI Friend - USB Serial Programmer Module for ESP32

Color: As shown Material: PC 1.UPDI stands for Unified Program and Debug Interface, but this board is so smol and cute that we will call it the Unusually Playful Device Interfacer and pat its head when it does a good job. It's designed to make programming modern ATtiny chips very easy because it has 3V or 5V power and logic select, power, and transmit indicator LEDs, and a quick cable for poking into a breadboard. 2.Unlike our simple UPDI version, this board is HV for High Voltage because it will let you send a quick 12V pulse to the UPDI like right before programming. This is required for when the chip is configured to use the UPDI pin as a reset or GPIO. This board will also let you 'unbrick' any chip configured for HV usage, you can use it to reset the fuses for Low Voltage programming. 3.This UPDI High Voltage Friend makes programming such chips very easy: (1)Select between 3V or 5V power and logic - the 3V regulator can source up to 500mA to run even big projects. (2)Internal 12V boost converter with analog switch that will send a pulse to the UPDI line when the RTS pin is toggled low. (3)CH340E USB Serial converter chip with cross-platform drivers (4)1K Loop-back Resistor between RX and TX Green power OK LED Red serial activity LED Color: As Shown Material: PC Package Contents: 1* Module 1* Cable(Random Color) Only the above package content, other products are not included.
