[Verified] STC15W402 development board

Overview

As usual, I got a few 15W402 chips and made a development version.

Several sets of pin headers are reserved. The top and bottom are all IO ports. The leftmost is the download port. Use a jumper cap in the middle to modify the P55 function to be Vref or GPIO. The right side is the OLED interface of the IIC protocol. The levels have been prepared. Conversion processing

The switch on the left is to control the operating voltage of the microcontroller. When it is only powered by the download port, please turn the switch to 3V3.

The board comes with a power indicator light and user/reset button, and the functions are switched by STC-ISP

PCB is compatible with 600mil DIP package and can be plugged into various development boards (?)

Please see the schematic diagram for specific precautions.

--------

The physical diagram is different from the PCB diagram due to the use of the super invincible puzzle method.

Similarly, due to paneling, the PCB does not display component numbers.

-----The project comes with comments-----

Can anyone provide me with a 1.8V precision reference source? I am using it for AC measurement. The reference power supply is VCC and VSS (3.6V). I need to raise the voltage.
In addition to the above questions, can anyone provide a 3.6V power chip? I use 8M, and the moderator who used 3.3 said it was unstable! The requirement is greater than or equal to 150mA. I hope the e
Newbie help: Use the miniusb interface of the stm32f4 board for communication
Hello everyone, I am currently using the discovery board of stm32f4. Now I need to use its miniusb interface to connect to the usb interface of one of my peripherals (dynamometer), and then receive th
I don't understand int * char *, please give me some advice.
We often use "abcde" and {1,2,3,4}, char *= "" to make a string, but we rarely use int * to make a string. Suddenly I want to know if we can use int *p= {1,2,3,4} to make a string. Experts, please giv
MCU interrupt problem
Hello, experts. I want to ask how to do it (design) after the 51 MCU exits the serial interrupt and I need to execute it from somewhere else immediately (of course, 2-4 instructions can be executed)?
Help! CCS configuration problem of C6711
I'm using TI's C6711 DSK and CCS 3.3, but I don't know how to use its parallel port to connect to a PC for simulation. I heard that I need to import it from the setup and find dsk6711epp/spp278/378. I
