What is it?

NanoUPDI: the smallest USB Type-C Serial UPDI programmer for your projects.

Features

• CH340E/CH340X USB to Serial converter: A compact version of the well-known WCH CH340x series, which doesn't require an external crystal oscillator.
• Compact Form Factor: At only 10 x 22 mm (excluding header pins), it is the smallest serial UPDI programmer on the market.
• VCC Voltage Selector: Easily switch between 3.3V (3V3) and 5V logic voltages with a simple flick of a switch.
• USB Type-C: Compatible with any USB Type-C cable that supports both power and data (USB 2.0 or greater). The reversible USB Type-C connector allows the cable to be plugged in either orientation, maintaining full functionality (data and power).
• 2.54mm Pitch Pin Header: Designed for right-angle (horizontal) pin headers with a 0.1" (2.54mm) pitch pin headers (breadboard compatible), it also allows for custom wires or connectors to be soldered based on your needs.
• Status LEDs: Includes a green LED for power (PWR) and a red LED that blinks during data transfer (TX).
• Inspired by Stefan Wagner's SerialUPDI Programmer.

It comes wrapped in clear heatshrink tubing to avoid accidentally shorting the pins or the onboard circuits while in use (USB-C cable not included).
