The G120E System on Module (SoM) based on LPC1788 120MHz ARM Cortex-M3 SoM with 16MB SDRAM and 4MB MB FLASH. Supported by TinyCLR OS. The G120E provides a variety of interfaces and connectivity options, all packaged at an optimized power, size and cost. The G120E SCMs are surface mount embedded controllers that are well suited for harsh or high vibration environments. In addition, the system supports industrial grade targeting embedded application requiring a wide temperature range.

  • 120 MHz 32-bit ARM Cortex-M3
  • 4 MB of Flash
  • 16 MB of RAM
  • 80 GPIOs
  • Ethernet TCP/IP, WiFi, and SSL

Why Choose an SCM?

Surface-Mount Compute Module

Surface mount compute modules are ideal for harsh or high vibration environments. A robust connection, space saving with soldering down a module. Simpler and faster automated assembly. Lower initial cost and time of setting up for mass production, Better mechanical performance under shock and vibration conditions.

Software Options

G120E is officially supported by our TinyCLR OS and the older .NET Micro Framework.
