• ESC protocols (PWM, Oneshot125/42, Multishot, Brushed, Dshot150/300/600 bidirectional)
• PPM, SBUS and CRSF Receivers
• Builtin ESP-NOW receiver and WiFi configurationread more...
• SPI and I2C gyro modules support (MPU6050, MPU9250, ICM20602, BMI160)
• Flight modes (ACRO, ANGLE, AIRMODE)
• Frames (Quad X)
• Betaflight configuration tool compatible (v10.8-v10.10)
• Configurable Gyro Filters (LPF, Notch, dTerm, RPM)
• Blackbox recording (OpenLog/OpenLager/Flash)
• Up to 4kHz gyro/loop on ESP32 with SPI gyro
• MSP protocol interface
• CLI Interface
• Resorce/Pin mapping
• In flight PID Tuning
• Buzzer
• Lipo voltage monitor
• Failsafe mode

Hardware:

• ESP32 mini board or ESP8266 Wemos D1 mini or similar
• MPU9250 SPI or MPU6050 I2C gyro (GY-88, GY-91, GY-521 or similar)
• PDB with 5V BEC
• Buzzer and some electronic components (optional).

Software:

• Betaflight Configurator (v10.8 to v10.10)
• CH340 usb-serial converter driver

1. Download and unzip selected firmware fromReleases Page
2. VisitESP Tool Website
3. Click "Connect" and choose device port in dialog
4. Add firmware file and set Flash Address to0x00
5. Click "Program"
6. After success power cycle board

Note: only ESP32 and ESP8266 can be flashed in this way.

After flashing you need to configure few things first:

1. Configure pinout according to your wiring, especially pin functions, you can find more information inCLI Reference
2. Connect toBetaflight Configurator and setup to your preferences,
3. Test motors without propellers
4. Have fun ;)

Here are more details abouthow to setup.

• ESP32 - recommended
• ESP32-S2 - experimantal
• ESP32-S3 - experimantal
• ESP32-C3 - experimantal, lack of performance, no FPU
• RP2040 - experimantal, lack of performance, no FPU
• ESP8266 - deprecated, may stop being developed
