Learn about your Carbon board as well as how to prepare and set up for basic use
Need
- Carbon
- Board based on the STM32F401RE Processor connected to a nRF51822 bluetooth controller
- USB to MicroUSB cable (x2)
- This is needed for serial console interface and USB-OTG (including DFU support)
- Switches
- Two switches are provided: RST to reset the STM32F401 chip, BOOT0 to enter the STM32F4 bootloader
- Pin headers (unpopulated)
- Tx/Rx UART for STM32F4 chip
- 5-pin SWD interface to STM32F4 chip
- BOOT0 and BOOT1 lines exposed
- 5-pin SWD interface to nRF51 chip
Optional
- Mezzanine Products
- These devices allow you to expand your experience with any 96Boards by adding peripherals and enhancing onboard components
The following subsections should describe how to get started with the Carbon using the release build shipped with the boards. The Carbon board is ready to use “out of the box” with a preinstalled version of the Zephyr RTOS.
| Component | Description |

| Clock speed | 84MHz maximum |
| SRAM | 96KB |
| Storage | 512KB onboard Flash |
| Wireless | nRF51822 Bluetooth |
| USB | 2 x Micro USB |
| Expansion Interface | 30 pin low speed expansion connector: +3.3V, +5V, VCC, GND, UART, I2C, SPI, GPIO x4 |
| Digital Out Voltage | 3.3V |
| Analog In Voltage | 0-3.3V |
| Analog Pins | 6 |
| LED | 1 x UART Tx, 1 x UART Rx, 1 x Power, 1 x Bluetooth, 2 x User LEDs |
| Button | RST (Reset the STM32F4), BOOT0 (Boot into bootloader for flashing) |
| Power Source | micro-USB |
| OS Support | Zephyr |
| Size | 60x30mm |
IMPORTANT NOTES
- Flashing the nRF51 chip requires a SWD programmer such as a ST-Linkv2 or Segger JLink
The Carbon comes preloaded with Zephyr on the STM32F4 and nRF51822 chips and can be up and running with a few simple steps:
- Connect the micro-USB cable to supply power to the Carbon. The board will begin to boot Zephyr immediately. You can use either of the micro-USB ports to power the Carbon.
