Open source four-axis remote control

1. Introduction:

A four-axis remote control designed based on Xiao Ma Ge's RoboFly open source four-axis software platform, open source four-axis: open source quadcopter

2. Remote control functions:

1. Main control STM32F103C8T6

2.SI24R01 wireless communication four-axis remote control, OLED four-axis attitude return display, voltage return display, one-key unlock function, etc.

3.Button function

Power light D1: It is the power indicator light, the remote control is powered on.

Signal light D2: Flashing - the four-axis and remote control are connected but not unlocked, steady on - the aircraft is unlocked.

Left joystick: The joystick moves up and down to control the ascent and descent of the four axes, and the joystick left and right controls the heading angle of the four axes.

Right joystick: The joystick moves up and down to control the forward and backward movements of the four axes, and the joystick left and right controls the left and right movement of the four axes.

Buttons: K1 is the unlock/lock button - the K1 button is only effective when the throttle is pulled the lowest, K2 is reserved, K3 is the sensor calibration button, and K4 is the mode selection.

2. The power supply is a 3.7V 1S lithium battery, which can also be powered by USB and has an SWD program download interface reserved.

3. Electronic amateurs cannot guarantee the standardization of PCB layout design, and the design needs to be improved.

4. No problems have been found during use. If you have any questions, please leave a message in the comment area below.
