STlink header has been refactored to have the same pinout as the MMDVM_HS_Hat boards. OLED and STlink header have been exchanged. JP1 has been slightly moved. C44, C45 and C46 have been relocated nearer to the STM32F1 CPU. A table was added to the bottom silkscreen to show which TCXO is installed. This is important to the firmware. BOM and Mouser cart are still the same. The stencil has slightly changed. If you manually solder C44-C46 you can still use the old one.
