Description
ZL41ARM is a single board computer with a STM32F207/217 microcontroller (Cortex-M3) or STM32F417 (Cortex-M4). The large number of available GPIO lines allows it to be used as a universal microprocessor system with high computational efficiency, thanks i.a. modern design and high frequency CPU clock.
Basic parameters
- STM32F207VE (ARM Cortex-M3, 512 kB Flash, 128 kB RAM), STM32F217VG (ARM Cortex-M3, 1024 kB Flash, 128 kB RAM) or STM32F417VG microcontroller (ARM Cortex-M4, 1024 kB Flash, 192 kB RAM)
- Oscillator 8MHz
- Microcontroller I/O lines available on pin connectors
- JTAG interface connector (20-pin)
- Power supply from USB port (mini USB)
- Jumpers for selecting the boot mode
- Reset button
- I2C and SPI connectors compatible with Kamami standard to connect additional modules
