User Manual Grid-EYE Evaluation Kit
3.1.9 Other Jumpers Definition
The following table explains several other headers on the evaluation kit.
Connecter Pin 1 Pin 2 Function
J7 TX UART_RX
Select to connect RX pin for ATSAMD21 USART1 with D1 for
Arduino and TX for PAN1740 UART.
J10 RX UART_TX
Select to connect RX pin for PAN1740 UART with TX pin for
ATSAMD21 UART
J13 D2 UART_CTS
Select to connect D2 for Arduino with CTS pin(hardware flow control)
for ATSAMD21 UART
J15 D3 UART_RTS
Select to connect D3 for Arduino with RTS pin(hardware flow control)
for ATSAMD21 UART
J9 D14 SCL
Select to connect SCL pin for ATSAMD21 I2C with SCL pin for Grid-
EYE sensor.
J12 D15 SDA
Select to connect SDA pin for ATSAMD21 I2C with SDA pin for Grid-
EYE sensor.
J8 D7 INT
Select to connect Arduino data pin D7 with Grid-
EYE’s interrupt
signal INT.
J6 5V
D2 negative
pole
Select 5V power from Arduino board.
J11 3.3V VDD3.3 Select 3.3V power from Arduino board.
J14 D6 RESET Select to connect D6 for Arduino with Reset pin for PAN1740
J18 GND PA15 Select to connect PA15 for ATSAMD21 to ground.
Jumper settings:
1. J7 and J10 are used to isolate the UART port for the ATSAMD21 microcontroller
when programming the Bluetooth module PAN1740, or engage the board into
Arduino mode.
2. J9 and J12 are used to set up the evaluation kit into either independent mode or
Arduino mode. When J9 and J12 are in-situ, the sensor and ATSAMD21 are
connected via I
2
C and the board works in independent mode. Removing the two
jumpers will enable the Arduino mode when the Grid-EYE board is hosted onto the
Arduino board. If not hosted onto the Arduino board and jumpers are removed
unexpected and undefined data will be received and/or transmitted.
3. When programming ATSAMD21 with SAM-BA, J18 is placed in-situ to update the
bootloader or start the application. By having the jumper J18 connected and the
reset button SW1 pressed, ATSAMD21 will be ready for updating the bootloader.
