The GD32 has a minimal voltage of 2.6, while the STM32 has a minimum voltage of 2.0 Volt. So there are cases where the GD32F103 won’t work when the STM32F103 does. Another difference between de GD32F103 and the STM32F103 is the maximum speed.
Jan 18, 2018 · Lets zoom into the STM32F103C8 chip (which seems the be the go-to choice of the Chinese el-cheapo development breakout boards): The GD32F103C8, manufactued by Gigadevice, has similar specifications and thus many people think the chip is a cloned version of the STM32 part.
Jan 19, 2018 · Just the GD32F103 part number may be a red flag because in this case it is obviously targeting the ST product line. There may also be licensing restrictions imposed by ARM as to how a licensee may use their IP.
Sep 22, 2020 · GD32F103 run at 108Mhz-8Mhz(crystal) not 72-8Mhz. If you change the xtal on the board for 12Mhz you can use old rogers core. Blinking will still work regardless of the Xtal used.
Jan 31, 2018 · For the STM32F103 vs GD32F103 challenge I needed to have two identical boards with a different microcontroller. As far as I could judge both chips are legit and not counterfeits as we bought both chips from (different) reputable sellers. The used chips are GD32F103CBT6 and STm32F103CBT7.
Mar 9, 2016 · The GD32F103xx device incorporates the ARM Cortex-M3 32-bit processor core operating at 108 MHz frequency with Flash accesses zero wait states to obtain maximum efficiency. It provides up to 3 MB on-chip Flash memory and up to 96 KB SRAM memory. Read more.
