Going to try out the #GD32E230 microcontroller by #GigaDevices. It's supposed to be at least somewhat compatible with the #STM32F030 by #STMicroelectronics but is available in several additional, physically small package types (QFN32 5x5mm, QFN28 4x4mm, LGA20 3x3mm).
I intend to use the LGA20 3x3mm but for trying out I soldered a TSSOP20 onto a generic breakout board.
