  GPIO Elements 

A pushbutton and an LED are included as options on Agora. Both of these components are application-

controlled; they can be programmed to function in whatever way the application calls for. These features can 

be used for development and/or in end-product applications.  

9.1.

 

 

GPIO Elements | Red LED 

Agora features an onboard red LED controlled by programmable a GPIO pin on the nRF52840 MCU. This LED is 

useful for development & debugging as well as for some end-product applications. The LED consumes a nominal 

current of 4.4mA. The control signal for the LED is active-low and is connected to pin A4 (P05) of the nRF52840.

GPIO Elements | Pushbutton 

Agora features an onboard pushbutton connected to a GPIO pin on the nRF52840 MCU. This pushbutton is 

useful for development & debugging as well as for some end-product applications. This pushbutton signal is active-

low. The pushbutton GPIO pin is pulled high to 3.3V through an external 1M ohm resistor. When pressed, the 

pushbutton connects the GPIO pin to COM (0V). The pushbutton GPIO pin is A2 (P29) of the nRF52840.

   Memory 

Agora supports onboard NOR flash packages controlled by the nRF52840 module. The flash module used in the 

default Agora configuration is the 32Mb QSPI NOR flash W25Q32JVZPIQ by Winbond. This flash module includes the 

following features: 

 

 

Supports JEDEC standard manufacturer and device ID and SFDP 

 

128-bit unique serial number 

 

Four 256-byte Dedicated Security Area with OTP user-lockable bits 

 

This flash module communicates with the nRF52840 MCU over QSPI lines using pins E1 (P20: IO0), E2 (P21: IO1), 

C2 (P22: IO2), D1 (P23: IO3), D2 (P19: CLK), and C3 (P17: CS#).
