1308

Overview

The Pololu 1308 is a CP2104 USB-to-Serial Adapter Carrier designed to bridge USB 2.0 Full-speed interfaces with TTL serial devices. It functions as a virtual serial port, enabling straightforward connectivity between personal computers and embedded systems requiring UART communication. The module integrates the Silicon Labs CP2104 chip, which handles protocol conversion internally. This carrier board provides a compact solution for developers needing reliable serial data transmission without complex driver configurations or additional interface hardware.

Feature Summary

Integrates CP2104 chip for direct USB to UART protocol conversion
Functions as a virtual serial port on host computers
Supports connection of TTL serial devices to standard USB ports

Applications

Connecting microcontrollers to PCs for programming and debugging
Establishing serial communication links in embedded system development
Interfacing TTL-level sensors or modules with computer-based monitoring software

Procurement Notes

Verify that the specific unit matches the Pololu part number 1308 and contains the CP2104 chipset. Confirm the physical package type aligns with the adapter carrier design rather than standalone IC packaging. Ensure documentation references the correct USB-to-serial functionality and not generic interface adapters.

Selection Notes

Select this module when a pre-assembled carrier is preferred over soldering a discrete CP2104 IC. It is suitable for applications requiring immediate prototyping of USB serial connections. Consider the form factor constraints relative to other USB-to-TTL solutions available from Pololu.

Part Context

This component belongs to Pololu's line of breakout boards and carriers that simplify the integration of complex integrated circuits into projects. The 1308 specifically addresses the need for easy USB connectivity in hobbyist and professional embedded electronics, leveraging the widely supported CP2104 technology.
