Overview
This page covers any general information for the Fly-E3-Pro-v3 board.
It is currently available through AliExpress.

- Drivers: Onboard TMC2209
- Drive mode support: TMC UART
- Support for 5 independent motor drives, 2 extruders, and 4 PWM fans
- All drivers support up to 24 volts.
- Supported Displays: serial touch screen, 12864 LCD, 2004 LCD , FLY 4.3, & 7.0 V1
- Supports automatic bed leveling sensor: BLTouch
- WiFi module supported with Reprap firmware.
- PWM Fan MOS boards can be directly replaced in case of damage.
Z Driver Jumpers
If only one Z output is being used, jumpers should be installed on the other Z output as shown below.
Driver Diag Pin
To use sensorless homing, a jumper must be installed on the diag header.
Power Configuration
The Fly-E3-Pro-v3 has two 24v inputs and one ground. The right 24v input powers the MCU and WiFi (as well as anything else that runs from 5v) and the left 24v input powers the motors, heaters and bed. This allows a relay to be used to turn off the motors, heaters and bed using a relay without having to use a separate 5v PSU to power the MCU. A diagragm can be found below.
Maximum Input voltage
The board can handle an input voltage up to 32v.
Thermistor inputs
The Fly-E3-Pro-v3 supports PT1000 on the thermistor inputs by using a 2k2 resistor rather than a 4k7.
Initial Installation
The board that you will receive doesn’t have any firmware installed so when plugged into a computer, the board will show as an unidentified device.
