Features
1. This core board for the pursuit of small volume for the single TYPE-C port design, USB function and serial port function for the two optional mutually exclusive design.
2. Small volume at the same time on both sides of the row of pins lead to all IO ports, and a separate lead to the SWD download port (both sides of the row of pins at the same time lead to IO ports), for small volume control program.
3. Easy to use, MINI32 can download the program through the on-board serial port.
4. High security, the chip has hardware encryption and access control functions to protect the security of the system.
5. Support for low-power modes, the chip supports a variety of low-power modes, which can realize energy-saving application design.

Core board for the pursuit of small size for a single TYPE-C port design, USB function and serial function for the two optional mutually exclusive design, welding U2 (CH340N) does not weld R4 and R5 when the C-port as a serial communication function, do not weld the U2 (CH340N) welded R4 and R5 when the C-port as a USB communication function to use.
About TYPE-C port CC port hardware design
CC1 and CC2 pins are empty: only USBA to TYPE-C port data cable can be used to supply power.
CC1 and CC2 pins are shorted and pulled down 5.1K resistor: when using fast charging source and double C-port data line with EMARK chip at the same time, no power will be supplied, and the rest of the matching can be supplied normally.
CC1 and CC2 pins respectively pull down 5.1K resistor: standard design, can be powered, recommended.
