FrSky flight controller XSRF4O and XSRF4PO overview

XSRF4O Features:
● Built-in F4 and XSR receiver module
● Built-in BARO BMP280
● Features the latest Accelerometer and Gyro technology.
● XSR receiver is a full duplex telemetry receiver, it will receive the commands of radios and send to F4 by SBUS (8CH is RSSI) to UART1 of F4, it can also send telemetry information back to radio by Smart Port.
● 6 PWM output signal lines for ESCs and Servos. Arranged for easy wiring on standard pin headers.
● OSD configuration has been included in Betaflight GUI.
XSRF4O Specifications:
● Dimension: 36*36*6mm(L*W*H)with 30.5mm mounting holes
● Weight: 7.7g
● Operating Voltage Range: 4.0-10V (recommend 5V)
● Operating Current 200mA@5V
● Number of Channels: 16CH(8CH is RSSI)by SBUS to UART1 OF F4, Smart Port of XSR to UART6 of F4
● Hardware: STM32F405 MCU, SPI Sensor, MPU6000, OSD, SD.
XSRF4PO Features:
● Built-in F4 and XSR receiver module
● Built-in onboard PDB up to 6S integrate with current sensor
● Features the latest Accelerometer and Gyro technology.
● XSR receiver is a full duplex telemetry receiver, it will receive the commands of radios and send to F4 by SBUS (8CH is RSSI) to UART1 of F4, it can also send telemetry information back to radio by Smart Port.

I own the XSRF40, and now I understand why you made the bass drop when it did 😂👌

[@0To400Feet]

Nice.

[@bitogre]

What is the max current that can be pulled through the PDB of the XSRF4PO to the ESCs? I want to make sure it can handle the power system I am thinking of using it with which may pull as much as 150Amp (burst).

Can you wire kiss 24a esc race editions on the XSRF4PO?

[@ChristopherNelson2k]

Where is UART 3 pad for smart audio?

STAY AWAY FROM THESE CONTROLLERS!!! JUNKS!!!! UNTIL THEY FIX THE FW ISSUE, DO NOT BUY THEM!!!

[@helnoSA]

Got a link describing the issue?

[@rolandhirschi2957]

firmware updating works very well, just use impulse driver fixer tool to generate a dfu connection
