Two green development boards with pin headers and USB-C ports

MCDODO

MCDODO STM32F411CEU6 Development Board 2Pcs 100Mhz 128KB RAM 512KB ROM

SKU CH-WNNQ-B1RBF

A two-pack of STM32F411CEU6 development boards with 100 MHz Cortex-M4 cores, 512 KB ROM, 128 KB RAM and 2.54 mm I/O headers for embedded projects

  • Product typeSingle Board Computers
  • ARM Cortex-M4 core runs at 100 MHz for fast processing
  • 512 KB flash and 128 KB RAM give ample program space
  • USB-C power input with 3.3 V LDO prevents backflow
  • 20-pin 2.54 mm headers plus 4-pin SWD simplify debugging
  • Two boards included so you can start multi-node projects

Purpose-built learning kit

This pack supplies two STM32F411CEU6 development boards aimed at students and engineers who want hands-on experience with an ARM Cortex-M4 core. Each board delivers a 100 MHz clock, 128 KB of RAM and 512 KB of flash for embedded firmware projects. The set is not suited for builders who need more storage or higher pin-count variants.

Thermals and power behaviour

The boards operate from a 3.3 V to 5 V input with an on-board 3.3 V LDO rated at 100 mA maximum output. A USB-C connector includes a diode to prevent power backflow during development. Typical current draw stays well within the regulator limit, so no active cooling is required.

Connectors and daily workflow

Each unit provides a 20-pin 2.54 mm I/O header, a 4-pin 2.54 mm SW debug header and tactile buttons for KEY (PA0), NRST and BOOT0. High-speed and 32.768 kHz crystal oscillators give reliable timing for USART, I2C, SPI and USBFS peripherals. The pin spacing suits standard breadboards and perfboard prototyping.

Questions about this item

How do I connect the 20-pin 2.54 mm I/O headers and the 4-pin SW debug header, and which step is often missed?

Solder the headers to the board, then wire the SW debug pins to a programmer; the step often missed is setting the BOOT0 button to enter programming mode before flashing.

What maintenance will the 3.3V LDO and the USB-C power diode need over time?

The LDO supplies up to 100 mA; keep the load within that limit and ensure adequate airflow so the regulator does not overheat. The USB-C diode prevents back-flow and needs no routine service unless physical damage occurs.

Which limit appears first when the board runs continuously at 100 MHz?

The 3.3V LDO’s 100 mA maximum output current is the first constraint; sustained high-speed operation with peripheral loads can reach that limit and cause voltage drop or thermal shutdown.
