- TX/RX activity LEDs - Visual confirmation of data transmission and reception for quick debugging
- Built-in ESD protection - Protects your USB port and connected devices from electrostatic discharge damage
- Low power consumption - Bus-powered from USB with minimal current draw, ideal for portable and battery-adjacent applications
- 1-5 day shipping, 7-8 day delivery from Bengaluru warehouse - Fast delivery across India with same-day dispatch available in Bengaluru
- Expert technical support included - Get wiring diagrams, driver installation help, and troubleshooting guidance from our engineering team
Project Ideas
- Arduino Pro Mini Programming: Use the CP2102 as a dedicated USB programmer for the Arduino Pro Mini. Connect TXD to RXD, RXD to TXD, DTR to DTR (through a 100nF capacitor for auto-reset), and upload sketches directly from the Arduino IDE without needing an onboard USB port.
- ESP8266/ESP32 Firmware Flashing: Flash NodeMCU firmware, MicroPython, or custom Arduino sketches onto bare ESP8266 (ESP-01, ESP-12) and ESP32 modules. The DTR and RTS pins can be wired to GPIO0 and RST for automatic boot mode entry during upload.
