Description
A small USB stick that gives your computer a serial (UART) port for microcontrollers. Use it to upload code to boards without USB, talk to GPS and Bluetooth modules from a terminal program, or read logs from a router or ESP module.
Features
- Silicon Labs CP2102 USB-to-UART bridge – stable drivers for Windows, macOS and Linux
- Baud rates from 300 bps to 1 Mbps
- Pins: DTR, RXD, TXD, 3V3, 5V, GND
- DTR pin enables auto-reset when programming Arduino Pro Mini
- TX/RX activity LEDs and a power LED
How to connect
Cross the data lines: adapter TXD → board RX, adapter RXD → board TX, and connect GND to GND. Power 3.3 V boards from the 3V3 pin only (it supplies a small current, about 100 mA) – ESP modules need a separate 3.3 V supply.
