This is a base board for the NZ32-SC151 STM32L151RC ARM Cortex-M3 module. It breaks out the module's pins into female sockets constituting four iMod ports, and also breaks out the programming pins to allow for in-circuit debugging with an ST-LINK/V2-compatible programmer. (It is not a standard pinout, so you will need to connect the lines individually.)
The base board's iMod ports have sockets to support either 0.7" or 0.9" width iMod Modules, or even double-width iMod modules like the im4OLED shown in the picture below.
Example Application This image shows the base board with an NZ32 module installed (middle) and three different iMod modules plugged in:
Configuration Jumpers The base board has several solder jumpers on the bottom allowing it to be used for different applications. It is supplied with default solder jumpers that configure the board as follows:
The board's schematic notes all the default solder jumper positions in blue.
- The Vcc pin (iMod pin 15) of all iMod ports is configured for 3.3V.
- iMod ports 1 and 2 are configured for SPI mode (pins 12, 13 & 14 of all iMod ports can be configured for I2C or SPI mode).
- iMod port 4 is configured for I2C mode (pins 12, 13 & 14 of all iMod ports can be configured for I2C or SPI mode).
