 +v1.2: general release. Changes:
 +
 +  * The [[wcore_usb|USB]] board is now combined with the wCore. It can be used as is or broken apart and the USB reconnected with wires, a 2.54mm header or a 10-pin Micro-MaTch connector.
 +  * Resistors R7B1-4 were renamed properly to R33A-D. R33**D** should have a different value (560~820R) than R33A/B/C (1k). Using longer cables on J15A/B and a smaller resistance for R33D could lead to displays not initialising properly. ​
 +  * There is a circular silkscreen mark that aligns with the same mark on the Waveshare breakout.
