STMicroelectronics STM32C0316-DK Discovery Kit offers alternative features to the corresponding NUCLEO-C031C6 board. The standard 20-pin layout of the STM32C0 microcontrollers are user accessible. Users can override the SWD debug pins by disconnecting the debug probe. Furthermore, the 5-way analog rock switch and LED can be overridden with a slide switch available to the user. The DIP28 connector permits all the pins to be available. The user chooses the header type. The 32768Hz onboard 1-pin clock generator for RTC allows cutting with a slide switch.
The STM32C0316-DK Discovery Kit helps migrate from 8‑bit to STM32C0 microcontrollers and between STM32C0 and STM32G0 microcontrollers.
The DIP28 pinout is developed to be as compatible as possible with the ATMEGA328 8‑bit microcontroller. The LQFP48 footprint is compatible with STM32G031/071/0B1 microcontrollers, while the UFQFPN20 footprint is compatible with STM32C01 microcontrollers. Lastly, the WLCSP20 footprint is compatible with STM32G051 microcontrollers.
The 5V to 3.3V regulator bypasses itself when its source exceeds 3.3V. The debug probe level shifters modify the debug signal levels to the target microcontroller supply voltage.
