Description

Our Kernel Masters Custom USB-TTL Converter brings you a robust and reliable USB-to-TTL interface module, engineered for embedded systems, development boards, firmware uploads, and maker education.

Featuring the proven CH340 USB-to-serial bridge chip, this module supports full-speed USB and presents as a COM port on Windows/Linux/macOS, making seamless integration with popular IDEs, serial terminals, and programming workflows. It also integrates a dedicated 12 MHz crystal oscillator for stable clocking, enhancing timing accuracy and compatibility with boards that rely on minimum 8 MHz operation.

Whether you’re programming an AVR, STM32, ESP32, or custom microcontroller setup, this converter supports both 3.3 V and 5 V logic levels, allowing direct interfacing with a wide range of target boards. Ideal for educational labs, prototyping, and production tasks — especially for the Kernel Masters Embedded AI / Microcontroller training ecosystem.

Key highlights:

• Plug-and-play: connect via USB, install CH340 driver if required, your OS detects it as a COM port.

• Switchable logic: Choose 3.3 V or 5 V I/O level to match your target device.

• Built-in protection and status LEDs for power, TX, RX.

• Compact module size, breadboard-friendly / PCB mountable.

• Includes the high-accuracy 12 MHz oscillator — particularly useful when programming boards that run at 12 MHz by design or require stable clock base.

Perfect for:

• Flashing bootloaders, firmware, serial debugging.

• Using with boards like custom AVR/STM32 boards, microcontrollers running with minimum 8 MHz.

• Embedded AI training labs at Kernel Masters: students quickly access microcontroller serial consoles and firmware upload.

• Makers, hobbyists and professional embedded developers alike.
