High-stability Silicon Labs CP2102-based USB to TTL converter. Features dual 3.3V/5V power outputs and full hardware handshaking for reliable firmware flashing and debugging.
Many cheap USB-to-TTL converters use counterfeit chips that "blue-screen" your PC or drop data packets at critical moments during firmware updates. The CP2102 USB 2.0 to UART Bridge is the industry standard for stability. Whether you are unbricking a router, programming an ESP32, or data-logging a sensor, this module provides a rock-solid transparent serial bridge that just works.
We understand that a failed flash can brick expensive hardware. That’s why every batch of our CP2102 modules is Probots QC-Pass, undergoing a visual and functional inspection to ensure no cold solder joints or misaligned components. Furthermore, this specific board revision is Probots LifeCycle Ready; we maintain a consistent stock of this exact pinout and PCB layout, making it a reliable choice for long-term industrial projects and educational kits.
Controller: Silicon Labs CP2102.
USB Standard: USB 2.0 Full Speed.
Baud Rates: 300 bps to 1 Mbps.
Output Voltages: Dual 3.3V and 5V power pins available.
Logic Level: 3.3V (5V Tolerant inputs).
On-board Indicators: Power LED, TX and RX data LEDs.
Integrated Features: 1024-byte EEPROM, integrated clock, and voltage regulator.
Temperature Range: -40°C to +85°C.
Microcontroller Programming: The go-to tool for Pro Mini, ESP8266, and ESP32 boards.
Router & Modem Recovery: Access the serial console of network hardware to fix firmware issues.
DIY Data Loggers: Stream sensor data from your workbench directly into Excel or Python via Serial.
PLC Interfacing: Bridging modern PCs to legacy industrial equipment via UART.
Past Projects (Prerequisites): If you’ve spent hours wrestling with CH340 driver signatures on macOS or Windows 11, this is your solution.
Feature Upgrade: The CP2102 unlocks higher reliability at high baud rates (up to 921600) and provides much cleaner 3.3V power compared to entry-level converters. It also includes the DTR pin, essential for the "Auto-Reset" feature required by the Arduino IDE.
Effort/Requirements: Beginner Friendly. Silicon Labs officially maintain drivers and are often pre-installed in modern OS kernels.
⚠️ Wiring Tip: Remember that UART is a "cross-over" protocol. TX goes to RX!

We are into electronics & mechanical projects in this connection we had contacted probots & we visited them , To our pleasant surprise , their presentation with us was friendly wrapped with professional support , which helped us to choose better , this interaction was patient & excellent .with all confidence i shall promote them to my known sources looking for components . Pls maintain this attitude towards customer this shall take your organization to heights
Great place to get all electronic components and accessories for electronic products.
I had ordered something, will write review after the order process is complete.
Ordered a couple of times, Bad Experience. They charge premium delivery fee but delivery will not happen on time(every time). And the resopnce after sales on the issues such as delivery is slow and not friendly. If you can take the delivery at your own risk, and liesure you can order.
I would like to share a suggestion based on my recent experience. I am also running a private limited company and understand how important customer relationships are. One key area that needs attention is training employees on how to deal with customers professionally and respectfully. No business starts with bulk orders—every relationship begins small and grows with trust. I had some plans to collaborate when I visited your facility, but unfortunately, due to the way I was treated, I decided not to proceed with any future business plans. I believe this is not a reflection of the owner, but rather an issue with employee conduct. Proper training and customer handling can significantly improve business growth and reputation. As I do not have a direct contact, I am sharing this feedback here. If you would like to discuss further, please feel free to contact me. Our recent bill was under the name Electro Instruments.
Fast Delivery, Accurate information, Quick resolution, most important acceptance & accountability and willingness to help.
