-  - These are the current-limiting resistors for the LEDs. The schematic shows a value of 5K6 but that seems a bit large/makes the LEDs too dim. Your mileage may vary.+  - These are the current-limiting resistors for the LEDs. The schematic shows a value of 5K6 but that seems a bit large/makes the LEDs too dim. Your mileage may vary. Draft v1.11 board specifies 1K.
