Having a few spare ST32F407 chips collecting dust, I decided to make a neat little board for it. Featuring USB, JTAG, microSD, 32Mbit spiflash, WiFi, 18 GPIOS with 3.3V / 5V bi-directional level translation for a special purpose 🙂
Cortex-M4 is a great ARM MCU running at 168MHz, 192KB ram and 1MB flashrom. The one in use is a ST32F407VGT in a TQFP100 package, all GPIO’s are routed, no components backside. Board size 76×66 mm.
Still waiting for my USB3.0 FPGA boards to arrive.
