SWM181CBT6_CoreBoard_V1.0

SWM181CBT6 core board
    On the occasion of the 2022 "Digital Intelligence Central Plains" Henan Province College Student Electronic Design Competition, the Henan Province Electronic Competition Organizing Committee also disclosed some competition information to everyone. The main control unit (MCU) is an important part that reflects the performance of a system. The SWM181CBT6 main control unit is an MCU recommended by this year's organizing committee. In this issue, we have open sourced a minimum system core board of Huaxin Weite SWM181CBT6. I hope it can be helpful to everyone! I hope everyone can achieve excellent results in this competition!
[Introduction to MCU performance and system board]
1. Chip introduction
SWM181 data sheet information, a brief introduction is as follows:
(1) Built-in 16KB SRAM, 120KB Flash;
(2) 32-bit ARM® Cortex™-M0 core, which can run at 48MHz;
(3) SPI x 2, UART x4, I2C*2, CAN*1;
(4) 8-channel 16-bit PWM generator;
(5) 12-bit 8-channel high-precision SAR ADC;
(6) 16-bit 6-channel high-precision SIGMA-DELTA ADC;
(7) 24MHz, 48MHz on-chip clock source with an accuracy of 1%.
2. Introduction to the system board
(1) The board is equipped with basic circuits based on MCU, such as crystal oscillator circuit and power conversion circuit;
(2) The core board introduces commonly used I/O port resources;
(3) It introduces the SWD simulation debugging download interface , you can use J-Link debugging simulation and downloader, which is convenient and simple;
(4) Overall size (805mil*2100mil), the distance between the two rows of pins is 600mil;
(5) System crystal oscillator of the core board (24.00MHz);
(6) It is equipped with a single row of pins with a pitch of 2.54mm to ensure excellent conductive contact and facilitate users to place the core board on a standard universal board or breadboard. Users can choose the welding direction according to their actual needs;
(7) Equipped with a Type-C printing interface, it is easy to use, sturdy and durable, and can be used for Type-C communication and power supply;
