Calliope Mini v3

Hardware

Platform platform_nordicnrf52: The nRF52 Series are built for speed to carry out increasingly complex tasks in the shortest possible time and return to sleep, conserving precious battery power. They have a Cortex-M4F processor which makes them quite capable Bluetooth Smart SoCs.

Microcontroller NRF52833
Frequency 64MHz
Flash 512KB
RAM 128KB
Vendor Calliope

Configuration

Please use calliopemini_v3 ID for projectconf_env_board option in projectconf:

[env:calliopemini_v3]
platform = nordicnrf52
board = calliopemini_v3

You can override default Calliope Mini v3 settings per build environment using board_*** option, where *** is a JSON object path from board manifest calliopemini_v3.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:calliopemini_v3]
platform = nordicnrf52
board = calliopemini_v3

; change microcontroller
board_build.mcu = nrf52833

; change MCU frequency
board_build.f_cpu = 64000000L

Uploading

Calliope Mini v3 supports the following uploading protocols:

  • blackmagic
  • cmsis-dap
  • jlink
  • stlink

Default protocol is cmsis-dap

You can change upload protocol using projectconf_upload_protocol option:

[env:calliopemini_v3]
platform = nordicnrf52
board = calliopemini_v3

upload_protocol = cmsis-dap

Debugging

piodebug - "1-click" solution for debugging with a zero configuration.

Warning

You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions and configuration information.

You can switch between debugging debugging_tools using projectconf_debug_tool option in projectconf.

Calliope Mini v3 does not have on-board debug probe and IS NOT READY for debugging. You will need to use/buy one of external probe listed below.

Compatible Tools On-board Default
debugging_tool_blackmagic Yes
debugging_tool_cmsis-dap
debugging_tool_jlink
debugging_tool_stlink
