Castellated MCU Development Modules

The myl-modules family is a set of compact, castellated microcontroller modules designed to be reflowed directly onto a carrier PCB, much like a Wi-Fi or Bluetooth module. Each module exposes the MCU's I/O, power, and debug pins along its edge, so you can design a carrier board around a proven, pre-validated MCU footprint instead of routing a full BGA or QFN yourself.

Three MCU platforms are available: Nordic nRF for Bluetooth Low Energy applications, Raspberry Pi RP2040 for general-purpose control with PIO peripherals, and STM32 for a broad range of performance and peripheral options. Each platform ships in a USB variant with an onboard USB connector for development, and a non-USB variant for space-constrained or production-only designs.

  • Castellated edges for direct reflow onto a carrier board
  • Pre-validated MCU, power, and crystal layout
  • USB variants for development; non-USB variants for production
  • Compatible with the IDE for Zephyr toolchain
  • Consistent pinout across the module family
