What makes it special?

Each bed segment can be discretely controlled with its own heater circuit, you no longer have to heat up the entire bed for smaller prints.

there are 3*3 separate zones each one have a thermistor that not only heating separately but also more even in heating than the normal print bed that have only one thermistor.

Bed Size:235*268**2mm

Print Size:220*220mm

Compatible with Creality ender3 serials.

Material: PCB FR4

Power input:24V

Power connector:XT60

Signal connector:I2C

communication protocol: Gcode,Sending heating Gcode M140 or M190,and then with G1 or G0 sending X and Y positon for example:

M140 S60  
G1 X100 Y10 

it will heating the second Zone where the position (100,10) is.

any board which has 2 free GPIO and run Marlin firmware. configure the 2 GPIO as software I2C port to communicate with Panda BED with Gcode.

The folder library is the I2C library allows to control PandaBed which is a I2C Segmented heat bed for 3D printer.

The folder Test_Panda_bed is a simple arduino platfromio project test example.
