MicroPython compilation information: https://github.com/WeActTC/WeAct_F411CE.git Product Introduction: Features: * Gold immersion process * The latest version is V3.1 For ARM Cortex M4: * Up to 100MHz operating frequency, fast access to memory * FPU (floating point computing) unit Memory: * 512KB ROM Flash Program Memory * 128KB SRAM Static Random Access Memory * SPI Flash (empty solderer) Clock and Power Supply: * 3.3V-5V power input, 3.3V LDO maximum output current 100mA * Use the USB C interface, with diodes in series to prevent power back-flow * 25Mhz 9pF high speed crystal oscillator * 32.768K 6pF low speed crystal oscillator Interfaces and buttons: * USART x 3, I2C x 3, SPI x 5, USBFS x 1 * ADC x 1 (10), I2S x 5, CRC x 1, TIM x 8 * 20 Pin 2.54mm pitch I/O interface x 2 * 4 Pin 2.54mm pitch SW debugging interface x 1 * USB C (type C) port x 1 * User key KEY (PA0) x 1 * Reset button NRST x 1 * BOOT0 button x 1 Design and Quality: * Using lead-free soldering process, PCB with gold immersion process * Set BOOT in the form of buttons * High-quality crystal oscillator with metal shell can start oscillation well * Always use original chips for ST Attention: * Github/Gitee regularly updates the batch number of chips used to ensure that you are buying brand new chips * No factory test program is provided to prevent the occurrence of counterfeiting Size: * Board size: 52.38mm x 20.78mm How to enter ISP (serial port/USB download): Method 1: * Press BOOT0 and NRST at the same time, release NRST, release BOOT0 after 0.5S, and then it can enter ISP mode Method 2: * In power-off state, press and hold BOOT0, power on, wait for 0.5S, release to enter ISP mode * Serial port download: use USB to serial port to connect PA9 and PA10 of the core board, do not use USB port for power supply * USB download: Just use a data cable to connect to a computer. If there is an unrecognized problem, you can properly heat the chip (25℃+), and then re-enter the ISP mode * Software: STM32CubeProg and WeAct Studio Download Tool WeAct Studio USB Download Tool: * Hold down the BOOT0 key and connect to a computer * Device Manager will show DFU devices * Input the file name of the firmware to be burned. For example, firmware.bin * Download Addr: 0x08000000 How to enter HID IAP (USB download): USB to serial port, debugger, and computer driver are not needed. Just use a TYPE-C data cable to download firmware 1. Burn the HID IAP firmware (it is a special test version, for the factory program is flashed by default) 2. Press and hold the KEY button to power on or press and hold the KEY button to reset, LED C13 flashes, release the button to enter 3. Confirm that the APP firmware address is 0x8004000, and the interrupt address offset is 0x4000 4.
