Summary This is the updated version for Darwin AIO We integrated the ELRS receiver on the FC to make it easier to apply to the mini Drone ESC adopts Bluejay firmware and is compatible with 1 3S Lipo input and the maximum current reaches 17A FC provides 2 sets of Uarts interfaces and at the same time provides various external devices interfaces such as SBUS Softserial CTR BUZZ RGB and so on which perfectly solves the problem of insufficient quantity of F411 Uarts Learn about ExpressLRS ExpressLRS is an open source Radio Link for Radio Control applications all of you can find these projects on GitHub it is based on the fantastic Semtech SX127x SX1280 LoRa hardware combined with an Espressif or STM32 Processor Using LoRa modulation as well as reduced packet size it achieves best in class range and latency It achieves this using a highly optimized over the air packet structure giving simultaneous range and latency advantages It supports both 900 MHz and 2 4 GHz links each with their own benefits 900 MHz supports a maximum of 200 Hz packet rate with higher penetration Under 2 4GHz frequency bands OpenTX system supports amazing 500Hz Specifications Brand DarwinFPVModel F411 15A ELRS AIOInput Voltage 1 3S LipoFC Main Control Chip STM32F411Gyro MPU6500OSD AT7456EBlack Box NoneBarometer NoneBluetooth NoneReceiver On board SPI ELRS 3 x Version 2 4G ReceiverBEC 5V 2AUSB Interface 1x Micro USBSerial Port UART1 UART2Soft Serial Port NoneRSSI NoneRGB Onboa
