PCB For STM32F103Cx Bluepill ARM development board

Description

PCB For STM32F103Cx Bluepill ARM development board Introduction: An improved version of the famous BluePill development board, compatible with most ARM/RISC-V MCUs in LQFP-48 packages. Compared with other versions on the market, it is fully pin-compatible, has higher reliability for DIY soldering tests. you use this link as soldering guide and bill of materials also included LQFP-48 packaged STM32/GD32/AT32 microcontroller chips, including but not limited to the following models: STM32F103C8T6 STM32F030C8T6 GD32F103C8T6 GD32F130C8T6 GD32F150C8T6 GD32F330C8T6 GD32F303CCT6 GD32E103C8T6 GD32E230C8T6 GD32VF103C8T6 AT32F415CBT7 AT32F413CBT7 AT32F421C8T7 AT32F425C8T7 The pin arrangements of these models are compatible and can all use this development board. Compared with other versions on the market, the improvements are as follows: USB replaced with direct plug MicroUSB, strong and durable The BOOT0 selection is changed to a button. Press and hold BOOT0 and then press NRST to enter the built-in Bootloader. The 32.768 crystal oscillator is replaced with a 3×8 package and is not soldered by default. The VBAT pin uses a 0R resistor to connect to the onboard 3.3V power supply The SWD interface sequence is changed to CLK, DIO, GND, 3V3
