Features

• STM32-VLB1 is a breakout board for the STMicro Discovery VL board with STM32F100RBT6

microcontroller (128k program flash, 8k RAM). Bare PCB with Discovery module sockets

provided. BOM and schematic available for download.

• Six GPIO port headers providing 8 data bits and 3V/5V power.

• Three async. serial ports. ComBoard footprints provide RS232-DTE (male), RS232-DCE

(female) and RS485 USART interfaces. Circuitry can be built on the board or added with

interchangeable ComBoard modules. Six ASPICE board footprints provide I2C, and SPI

expansion signals on 14-pin headers. SD card connector footprint provided.

• Mostly thru-hole construction allows for easy assembly and expansion (optional power input,

JTAG header and SD card have SMT parts).

• 2-layer, FR4 glass-epoxy PCB, 1oz/ft2 copper. Soldermask & silkscreen. Lead free and RoHS

compatible. 6.30 x 6.30in (160 x 160mm).
