|
||||
* Description: This board has onboard USB (provided by the MCU).
|
||||
* It supports automatic firmware upload and serial over USB.
|
||||
* No onboard display. Optionally an external display con be connected.
|
||||
*
|
||||
* Onboard LED and SPI SCK use the same GPIO (13) which causes a hardware conflict.
|
||||
* Fortunately SCK can be remapped to a different GPIO (14).
|
||||
*
|
||||
* Connect an optional display according to below connection details.
|
||||
*
|
||||
* CONNECTIONS AND PIN DEFINITIONS:
|
||||
*
|
||||
* Indentifiers between parentheses are defined in the board's
|
||||
* Board Support Package (BSP) which is part of the Arduino core.
|
||||
*
|
||||
* Leds GPIO
|
||||
* ---- ----
|
||||
* LED <――――――――――> 13 (LED_BUILTIN) (SCK) Hardware conflict.
|
||||
* Cannot use LED_BUILTIN and SCK together.
|
||||
*
|
||||
* I2C [display] GPIO
|
||||
* --- ----
|
||||
* SDA <――――――――――> 18 (SDA)
|
||||
* SCL <――――――――――> 19 (SCL)
|
||||
*
|
||||
* SPI/LoRa module GPIO
|
||||
* --- ----
|
||||
* MOSI <――――――――――> 11 (MOSI)
|
||||
* MISO <――――――――――> 12 (MISO)
|
||||
* SCK <――――――――――> 14 NOT SCK!
|
||||
* SPI SCK is remapped to GPIO14 because
|
||||
* SCK definition conflicts with onboard LED.
|
||||
* NSS <――――――――――> 10
|
||||
* RST <――――――――――> 9
|
||||
* DIO0 <――――――――――> 8
|
||||
* DIO1 <――――――――――> 7
|
||||
* DIO2 - Not needed for LoRa.
