Quantity : 1 High-concerned chemical : none Package : SMD is_d : Yes Dissipation Power : STM32F103C6T6 STM32F103C8T6 CH340 Development Board Supply Voltage : 3.3V 5V Type : Module Brand Name : Gaqqee Operating Temperature : 0-50C Origin : Mainland China Condition : New

Features: 1. This core board pursues a small size with a single TYPE-C port design, and the USB function and serial port function are designed to be mutually exclusive. 2. For small volume control schemes, all IO ports are simultaneously led out on both sides of the needle arrangement, and the SWD download port is separately led out (both sides of the needle arrangement IO ports are simultaneously led out). 3. Easy to use, MINI32 can download programs through the onboard serial port. 4. High security, the chip has hardware encryption and access control functions, which can protect the security of the system. 5. Support low-power mode, the chip supports multiple low-power modes, which can achieve energy-saving application design. Parameter: TYPE-C: Choose between power input or USB/serial port (CH340) Buttons: RST (reset button), BTO (BOOT mode selection button) LED: PWR (POWER indicator light), C13 (user controlled indicator light, PC13 controls LED cathode) PCB dimensions (excluding SWD download port): 25.40 * 22.86MM (100MIL=2.54MM) PIN spacing: 2.54MM; Needle spacing on both sides: 15.24MM (600MIL) on the inner side, 20.32MM (800MIL) on the outer side Style 1: Main controller: STM32F103C8T6 Specification: STM32F103C8T6 (without CH340) STM32F103C8T6 (with CH340) Download methods: SWD/serial port, SWD C port function: serial port, USB Core: ARM Correx-M3 Main frequency: 72MHz SRAM[KB]：20 FLASH[KB]：64 C-port power input: 5V@500MA PIN POWER:5V/ 3.3V@500MA Style 2: Main controller: STM32F103C6T6A Specifications: STM32F103C6T6A (without CH340) STM32F103C6T6A (with CH340) Download methods: SWD/serial port, SWD C port function: serial port, USB Core: ARM Correx-M3 Main frequency: 72MHz SRAM[KB]：6 FLASH[KB]：32 C-port power input: 5V@500MA PIN POWER:5V/ 3.3V@500MA Style Three: Main controller: CH32V103C8T6 Specification: CH32V103C8T6 (without CH340) Download methods: SWD/serial port, SWD/USB C port function: serial port, USB Kernel: RISC-V3A Main frequency: 80MHz SRAM[KB]：20 FLASH[KB]：64 C-port power input: 5V@500MA PIN POWER:5V/ 3.3V@500MA Note: PIN TO PIN pin compatible chips are applicable to this core board and are not limited to a single MCU. If conditions permit, please try to use domestically produced MCUs. The core board pursues a small size with a single TYPE-C port design, and the USB and serial port functions are mutually exclusive. When U2 (CH340N) is soldered without R4 and R5, the C port is used as the serial communication function, and when U2 (CH340N) is soldered without R4 and R5, the C port is used as the USB communication function. Regarding the hardware design of TYPE-C and CC ports Both CC1 and CC2 pins are suspended: only USBA to TYPE-C data cables can be used for power supply. Short circuit CC1 and CC2 pins and pull down 5.1K resistor: When using fast charging power supply and dual C-port data cable with EMARK chip at the same time, power supply will not be provided, and other combinations can provide normal power supply. Pull down 5.1K resistors on pins CC1 and CC2 respectively: standard design, both can be powered, recommended for use. Package include: 1X Core Board label:yes
