the bat board rev3

2 layer board of 1.41 x 0.71 inches (35.7 x 17.9 mm)
Uploaded: October 30, 2017
Shared: November 20, 2017
Total Price: $4.95

A teensy-sized breakout board for QFP-48 STM32 MCUs (rev3). Originally designed for STM32L052CxTx, but should work with any pinout-compatible MCUs (most of LQFP-48 packaged STM32s should work, but check the datasheet! Tried with STM32L052C8T6, STM32F072CBT6, STM32F103C8T6).

Intended for low-power applications (e.g. sensors).

Features:

  • hand-solderable (0603, SOT-563 regulator, LQFP-48 (0.5mm pitch) MCU)
  • power options (USB <-> solder jumper <-> VIN <-> regulator <-> solder jumper <-> VDD net) - so it is possible to bypass the voltage regulator entirely; or add a LIPO-charger external module.
  • analogue supply optionally routed through a ferrite bead, and a footprint for an extra stabilising capacitor
  • 1 LED, reset button, user button (routed to BOOT0 and PA1) {hence the user button can be used to enter the built-in bootloader}
  • a footprint for adding an external high-frequency crystal (required for STM32L1* for USB)

      Ordering shared project

      Hey there! Before ordering, make sure you have all the info you need to complete and use this design. This usually means a component list, and sometimes additional information such as assembly notes, source code, or usage guides.
      Since this is a project designed by a community member, it may contain design errors that prevent it from working as intended. OSH Park cannot place any guarantees about the functionality or correctness of the design.
