Frsky XSRF3O, XSRF4O and XSRF3PO, XSRF4PO – FC with RX

Now almost every manufacturer has his own F3/F4 flight controller. Frsky went even further – four new Frsky flight controllers, integrated with receivers, were released. XSRF3O and XSRF4O are the 30.5x30.5mm mount hole format flight controllers, powered with F3 and F4 MCU respectively and have XSR receiver integrated. Also they have Betaflight OSD, S.Port and SD card slot. XSRF3PO and XSRF4PO are the flight controllers with prolonged boards (60x36x6mm with 30.5x30.5mm mounting holes) also powered with F3 and F4 MCU but also have on-board PDB, capable up to 6S with integrated current sensor.

Other differencies: XSRF3O and XSRF3PO use? MPU6050 gyro with I2C interface (speed up to 4KHz), ?while XSRF4O and XSRF4PO use? MPU6000 with SPI interface (speed up to 8KHz). Also?XSRF4O has?BMP280 barometer on board.
