Calliope Mini v3

Hardware

Platform Nordic nRF52: 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 board option in “platformio.ini” (Project Configuration File):

[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 upload_protocol option:

[env:calliopemini_v3]
platform = nordicnrf52
board = calliopemini_v3

upload_protocol = cmsis-dap

Debugging

Debugging - “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 Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

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
Black Magic Probe		Yes
