7-axis 3D Printer Motherboard Klipper Firmware Flexible Configuration
## Project description
SPARROW-7z 3D printer motherboard, main control stm32f103c8t6\cbt6, f103c6t6\c6t6a or f031c6t6, supports mainstream drivers such as A4988, TMC2208, 2209, TMC2225, 2226, all-axis uart (the first 4 axes are independent uart, and one of the axes cooperates with the rear 3-axis realizes full-axis uart through addressing uart), thermal leakage protection, mos tube protection, etc., small size 100mm*80mm. Considering that the DC chip is in a QFN package and is difficult to solder, you can choose to copy the SPARROW-7z_Lite version, which cuts off the 5vDC output and changes it to 5v input. The system power supply of the Lite version is provided by the host computer. If you use the RGB function, you must provide an external 5v power supply, otherwise The host computer may not be able to carry the RGB light strip.
## Kind tips
Power on, please check the power supply, the driver do not connect the reverse otherwise there is a risk of explosion board, replace the drive or plug and remove the motor line, please power off the operation otherwise there is a risk of burning MCU, explosion drive, led and fan interface check whether there is a short circuit connection or power-on tube!!
## Open source agreement
CC-BY-NC-SA 4.0
## Parameter:
* High-power heated bed control all the way
* One way heating head control
* Four-way limit (reused by software limit)
* Four-way fan or LED switch control (one way is multiplexed by RGB)
* One way rgb (multiplexed)
* 3-channel thermal temperature measurement (one channel is reused by bltouch)
* probe (reused by bltouch)
* BLtouch (reuse)
* One 5vDC output (Lite version is 5v input)
**(Reuse) means that only one function can be selected.**
