USB or SWD must turn off the battery power source when connected. -Add reverse battery protection mosfet | No. Better use solder jumpers to fix board assymetry. -Make YJ-14015 mounting area detachable (tearable) from the board in case we don't need it | Maybe. -I2C slot overlaps SWD slot, how to connect both display and SWD ??? Fix the overlap? | No. You don't really need that since there's no realtime debugging anyway. -Add mounting holes for people that cut acrylic cases | Fine. - -## TRRS - -``` -jian: - -SCL - T -SDA - R -GND - R -VCC - S - -keebio: - -T - VCC -R - SCL -R - SDA -S - GND -``` +* YJ-14015 (nRF51822-CoreB), 4-pin SWD header +* Reversible I2C display (SSD1306) support +* Reversible 03962A Li-Po charger board support +* CR2032 BS-7 battery holder support +* Manufactured by Elecrow +### Screenshot +![](images/jorian-1.0.jpg) diff --git a/images/jorian-1.0.jpg b/images/jorian-1.0.jpg new file mode 100644 index 0000000..14a6d33 Binary files /dev/null and b/images/jorian-1.0.jpg differ
