Hardware requirements¶
Besides the required hardware to start the corresponding platforms, Mira has some extra hardware requirements
- 32.768kHz crystal oscillator - needs to be connected. Stable within temperature range at +/-250ppm
- high frequency crystal, as required for radio peripheral
nRF52832¶
- Follow requirements from Nordic Semiconductor
- If the hardware does not have DCDC inductors, configure to use LDO. See provided "custom_module" example.
nRF52840¶
- Follow requirements from Nordic Semiconductor
- If the hardware does not have DCDC inductors, configure to use LDO. See provided "custom_module" example.
MKW41Z¶
- Internal load capacitors are disabled, add external capacitors to load the crystals
