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 19, 2018 · Any ARM-based microcontroller is going to have the ARM core itself plus a whole slew of peripherals (DMA engines, SPI/I2C, etc.). It’s remotely possible all the peripherals on the real STM32F103 are licensed from ARM and hence could be (in theory) also licensed by the GD design.
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 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.
Jun 22, 2018 · Sjaak writes, “This is part 4 in the series where we compare the STM32F103 with its Chinese counterpart the GD32F103. Both are ARM Cortex M3 microcontrollers which are mostly pin, peripheral and register compatible. Now we compare the SPI master peripheral of both chips.” More details at smdprutser.nl. Check out the video after the break.
Mar 26, 2018 · Here’s the part 3 of Sjaak’s post comparing the GD32 to the STM32: Since the GD32F103 can run as fast as 108MHz but has not a proper USB clock divider to provide a 48MHz clock for USB communication we need another way to communicate with the outside world.
