[Training Camp_Basic Class] Based on STC15FK Learning Board +588737A

The learning board is equipped with four LED lights, three touch buttons, two servo interfaces, an OLED screen interface, an ultrasonic module interface, and a Bluetooth module interface. The learning board is equipped with a USB to TTL download circuit, which saves the trouble of external download circuit and facilitates debugging. There is also an infrared receiver, which is convenient for use with an infrared remote control. The overall learning board is biased toward the direction of the smart car and can be used as a control circuit for the smart car.

Now this version of the PCB adds a DS18B20 for measuring temperature and improving the function of the learning board.

PCB improvements in the previous version: Silk screen position is unreasonable (modified); No DS18B20 (DS18B20 added); CH340 TXD and RXD have problems connecting to the microcontroller (corrected); Download button layout is unreasonable (improved); Infrared acceptance The header is not connected with a short-circuit cap in series (add a short-circuit cap, and remove the short-circuit cap when not in use to avoid affecting the microcontroller); There is no PCB fixing hole (two fixing holes are added to facilitate the installation of the shell later).
