Schematic updates for the V1.7 production run. Changes to: USB connection (dropped OTG, slave device only, 5V power now connected) Dropped interrupts from I2C devices to facilitate routing Swapped to BME280 temperature, pressure and humidity sensor Added input protection diode and increased capacitor on DC input to allow use of AC supplies Changed STM32 pinouts to allow UART/USART bootloader use (I2C didn't work in V1.6) Grounded latch pin from DAC, missing from V1.6 schematic.
