Description

For detailed documentation, see this product's Wik page.

This small board is designed for very low power applications. It is assembled with a STM32L151RC Microcontroller. It has an on board battery charger for a 3.7V Li-Ion or Li-Polymer battery. System 3.3V is generated via an on board 3.3V regulator with very low current consumption. This regulator provides 3.3V at 800mA which is available for any custom circuitry.

This board has 3 iMod port for adding Modtronix iMod modules. A common use for this module is to add a LoRa SX1276/SX1278 Wireless iMod module for battery powered, low power wireless applications.

Board can be powered via USB connector, external battery(plugged into JST PH 2.0mm connector) or external 5V provided via pin headers. If higher voltage is required, the pm35SS-5 iMod module can be added, allowing up to 28V supply. This can for example be connected to solar panels to power and charge the battery.

We are in the process of adding this board to available platforms on mbed.org. This will enable online programming using the free mbed compiler. Additionally online projects can be exported an built on local computer using free IDE(CoIDE) and free GNU GCC ARM C/C++ compiler.

Features

  • STM32L151RC Ultra low power CPU, optimized for low power applications (compatible with other STM32L151 and STM32L152 chips).
  • 256K Flash, 32K RAM, 8K EEPROM.
  • 3 x UART/USART ports, 2 x I2C ports, 3 x SPI ports.
  • 1 x Micro B USB Port.
  • Reset and Boot button.
  • 2 LEDs, one for indicating when battery is charging, and a user LED.
  • Firmware upgradable via USB port. If boot butter is pressed at power up(reset), board goes into bootloader mode.
  • Very low power 5V to 3.3V switch mode regulator with 16uA operating, and 0.01uA standby current.
  • Switch mode can be disabled by CPU, resulting in 0.01uA current, which is sufficient to run CPU for minutes in low power mode (run from power stored in Capacitors).
  • On board 3.7V LiPo (lithium polymer) or Li-Ion(Lithium-Ion) battery charger, and standard 2.0mm JST PH connector (many LiPo batteries have this connector). LED indicates when battery is charged. Can be charged from USB or 5V pin headers.
  • Hardware for monitoring input and battery voltage.
  • Additional regulator output capacitors to allow board to run for longer when switch mode is in standby mode (ultra low power 0.01uA operation).
  • Standard 2.54mm (0.1") pin headers.
  • Compact size 25.5 x 47.1mm
  • Breakout board for STM32L151RC, STM32L151 and STM32L1 development

Software Development & Examples

We provide a free template download with integrated mbed API, using the free System Workbench for STM32 or CoIDE IDEs(integrated development environment). Both these IDEs use the free GNU ARM GCC C/C++ compilers. This download has the mbed API and STM32CubeL1 Drivers integrated, meaning any of the large number of mbed or STM32Cube example programs can be used.

For details and examples(Digital read/write, Analog read, UART, I2C, SPI...), see this product's Wik page.

Programming and Debugging


Click to Enlarge

This board can be programmed using the following methods:

  • Using the STM32 built in USB or UART Bootloader.
  • Using the Modtronix PGM-NUCLEO programmer and debugger. Programming is via ST-LINK/V2-1 or Drag and drop. Additionally a USB virtual com port is provided for debugging.

Prototyping & Expansion


Click to Enlarge

We provide many different types of expansion boards making prototyping and product custimization easy. For example, this board can be combined with any of our many available iMod modules to add functionality like Relays, Opto Inputs, MOSFET outputs, CAN Bus, RS-485, RS-232 and more.

For details, see this product's Wik page.

 

Wireless Interface


Click to Enlarge

This board has 3 Modtronix iMod ports. This enables a wireless interface to be added to the board, like WiFi, Bluetooth or SX1276/SX1278 LoRa Wireless module. The SX1276 incorporates Semtech's LoRa technology, making very long range communication (over 10km) possible at low power! The photos below shows the NZ32-SC151 with an inAir SX1276/SX1278 LoRa iMod assembled. The inAir modules are available in 433MHz, 868MHz and 915MHz.
