⚡ At a Glance
- • Data Rates: 300 bps to 1.5 Mbps baud range for slow sensors up to faster serial links
- • Best for: Hobbyists, students and embedded developers programming microcontrollers and TTL peripherals
- • Not ideal for: Projects requiring native USB-C connectors or integrated USB hubs
CP2102-based USB 2.0 to TTL UART bridge with standard USB-A plug and TTL 5pin header. Dual-pack includes Dupont wires and wide OS compatibility.
Quick PC-to-microcontroller connection - with CP2102 USB 2.0 bridge
CP2102 chipset converts USB 2.0 traffic into TTL-level UART and exposes a virtual COM port to the host. A standard USB-A male connector and TTL header provide direct physical connections to targets.
Plug a module into a laptop USB port and TXD/RXD pins connect directly to a microcontroller for immediate serial access. Ideal for flashing firmware, serial monitoring and simple board-level debugging.
Flexible serial speeds - thanks to 300 bps to 1.5 Mbps baud range
Baud-rate support spans from 300 bits per second up to 1.5 megabits per second, accommodating slow telemetry devices and faster console links. The CP2102 handles USB packetisation and clocking internally to maintain stable transfers.
Match baud settings to target hardware for reliable data exchange across a variety of embedded use cases. Useful when switching between legacy sensors and modern microcontrollers.
Straightforward wiring and compatibility - with five-pin TTL header and Dupont cables
TTL 5pin connector lists labelled signals including 3.3V, RST, TXD, RXD, GND and 5V, and modules include Dupont wires for breadboard-friendly connections. Drivers are provided for Windows, Mac OS and Linux as specified by the manufacturer.
Wire up targets quickly without soldering; having power and reset lines simplifies programming cycles. Broad OS driver support reduces time spent on setup across different machines.
