Product Descriptions

This product is an STM32F030F4P6 microcontroller development board, equipped with an RT9193-33PB voltage regulator chip that can provide a maximum current of 450MA. It can convert 5V power supply from 5V USB to 3.3V voltage for powering the chip; The development board comes with a MICROUSB interface, which can provide power to modules and also has communication capabilities; Support the use of J-LINK and ST-LINK to download programs; Reserve a serial download interface for easy connection with the 5VWUSB to serial module, allowing for program downloads through the serial port; Reserve B00T selection port, which can be configured and selected using jumper caps. A large number of 1/0 pin sockets are reserved on the board and equipped with corresponding silk screen instructions, providing convenience for developers to use.

Product Functions

3： Serial port module burning method

1. BOOT setting: Two jumper caps on the BOOT position of HW-538PCB, with BOOT0 set to 3.3V, BOOT1、 Set GND as shown in the figure. (Note: In serial mode, if the BOOT mode is set incorrectly, the burning will not succeed.)

2. Serial port connection: The PA9 port on the PCB is connected to the RX on the serial module, the PA10 port is connected to the TX on the serial module, the GND is connected to the GND on the serial module, and the 3V3 is connected to the 3.3V on the serial module (it is also possible to supply 5V to the Micro USB of HW-268, so 3.3V does not need to be connected, but GND still needs to be connected) (TXRX needs to provide a 3.3V signal)
