Tested MCU
- WCH: CH32V203C8T6
- STMicro: STM32F103C8T6
X32Micro v1.2.0
feature
difference from v1.1.1
- Arduino UNO R4-like SWD with UART 1.26mm 10-pin added. VCC is 3.3V.
- Added Fuse to power supply.
- Damping resistor added to USB DM/DP
- Added pull-up resistor on USB DP to indicate USB 1.1 Full Speed
- Omit the LowPower crystal (because the built-in RC clock can be used).
- Omitted the BOOT0 button (since it is rarely used) and added through-hole access to BOOT0 and 1
- Changed pin assignments

- 電源に Fuse を追加
- USB DM/DP にダンピング抵抗を追加
- USB DP に USB 1.1 Full Speed を示すプルアップ抵抗追加
- LowPower 用クリスタルを省略（内蔵 RC クロックが使えるので）
- BOOT0 ボタンを省略（滅多使わないので）して、BOOT0、1 をスルーホールでアクセスできるように
- ピン配置変更
