SubGhz transceiver daughter board based on SPIRIT1 with PA (169 MHz band)

The STEVAL-IKR001V7D demonstration board is based on the SPIRIT1, a sub GHz low power, low data rate transceiver suitable for ISM bands and wireless M-BUS systems.

The STEVAL-IKR001V7D includes an external power amplifier from Skyworks®, which allows the application to reach +27 dBm (500 mW) output power.

This daughterboard is compatible with the STM32L microcontroller-based motherboard used in all other SPIRIT1 development kits.
