# ESP-FC Flight Controller
The mini, DIY, Low cost, ESP32 based, high performance flight controller for hobbyists.
# Features
* Espressif targets (ESP32, ESP32-S3)
* ESC protocols (PWM, Oneshot125/42, Multishot, Brushed, Dshot150/300/600 bidirectional)
* PPM, SBUS, IBUS and CRSF Receivers
* Builtin ESP-NOW receiver and WiFi configuration [read more...](/docs/wireless.md)
* SPI and I2C gyro modules support (MPU6050, MPU9250, ICM20602, BMI160)
* Flight modes (ACRO, ANGLE, AIRMODE)
* Frames (Quad X)
* Betaflight configuration tool compatible (v10.10)
* Configurable Gyro Filters (LPF, Dynamic Notches, dTerm, RPM)
* Blackbox recording (OpenLog/OpenLager/Flash)
* Up to 4kHz gyro/loop on ESP32 with SPI gyro
* MSP and CLI protocol interface
* Resorce/Pin mapping
* In flight PID Tuning
* Buzzer, Led and voltage monitor
* Failsafe mode
# Documentation
In this repository you can find firmware code that allows you to build your own flight controller. For convenience it mimics Betaflight 4.2 compability, so that it can be configured using [betaflight-configurator](https://github.com/betaflight/betaflight-configurator). Also [online blackbox-log-viewer](https://blackbox.betaflight.com/) can be used to analyze blackbox logs. In most aspects it is similar to Betaflight, so that many configuration and tuning advices are helpfull here too. But you must be aware, that this software is not the same as Betaflight, there are some limitations and differences in functionality and performance.

# Quick Start
## Requirements
Hardware:
* ESP32 or ESP32-S3 board
* 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](https://github.com/betaflight/betaflight-configurator/releases) (v10.10)
* [CH340 usb-serial converter driver](https://sparks.gogo.co.nz/ch340.html)
## Flashing
1. Download and unpack selected firmware from [Releases Page](https://github.com/rtlopez/esp-fc/releases)
2. Visit [ESP Tool Website](https://espressif.github.io/esptool-js/)
3. Click "Connect" and choose device port in dialog
4. Add firmware file and set Flash Address to `0x00`
5. Click "Program"
6. After success power cycle board
## Setup
After flashing you need to configure few things first:
1. Configure pinout according to your wiring, especially pin functions, you can find more information in [CLI Reference](/docs/cli.md)
2. Connect to [Betaflight Configurator](https://github.com/betaflight/betaflight-configurator/releases) and setup to your preferences,
3. Test motors without propellers
4. Have fun ;)
> [!NOTE]
> Not all functions displayed in configurator are avalable in firmware. The rule of thumb is if you cannot change specific option in Betaflight Configurator, that means it is not supported. It usually rolls back to previous value after save. It is strongly recommended to follow [setup guide](/docs/setup.md).
