V1a breaks out PA15 and changes the 32kHz crystal to a larger and cheaper ABS6.
An STM32L4 microcontroller in a Teensy form factor. This board was designed as a 2-layer PCB with all components on the top side as a more cost-effective, very low power Cortex M4 alternative. Design inspired by Kris Winer’s Dragonfly and Paul Stoffregen’s Teensy.
Includes both low-speed and high-speed oscillators, a supercapacitor RTC backup, an extremely low Iq LDO regulator, and flash memory. The supercapacitor’s VBAT pin is broken out such that an external coin cell or supercapacitor may be used.
