## Pinout

|
|
@warning Unlike on other ATmega MCUs, the GPIOs are not 5V tolerant.
|
||
|
|
|
||
|
|
@note The 5V pin cannot be used to power the board, as the board is not
|
||
|
|
equipped with an voltage regulator. The pin is therefore not
|
||
|
|
connected. But it can be used to pass 5V to shields, if connected
|
||
|
|
to a 5V supply voltage.
|
||
|
|
|
||
|
|
## Board
|
||
|
|
The Zigduino board is an Arduino-compatible microcontroller platform that integrates
|
||
|
|
a SOC with a 8-Bit AVR MCU and a IEEE 802.15.4 radio chip (ATmega128RFA1).

|
|
The MCU comes with a 2.4 GHz IEEE 802.15.4 radio that is compatible with the
|
||
|
|
Atmel AT86RF23x line of transceivers with the only difference being that it is
|
||
|
|
not being accessed over an SPI bus, but instead the radio registers are directly
|
||
|
|
mapped into memory.
|
||
|
|
|
||
|
|
# Flashing RIOT
|
||
|
|
Flashing RIOT on the Zigduino is done using the on-board USB-TTL adapter.
|
||
|
|
The ATmega bootloader is present on the MCU.
|
||
|
|
Simply use
|
||
|
|
|
||
|
|
`make flash BOARD=zigduino`
|
||
|
|
|
||
|
|
# Use on IoT Lab
|
||
|
|
|
||
|
|
Most of the Zigduino nodes are deployed in the Strasbourg site with sensors.
|
||
|
|
Some of these nodes are also combined with a LoRa modem in order to offer a dual radio stack IEEE 802.15.4/LoRaWAN.
|
||
|
|
|
||
|
|
There are two available configurations:
|
||
|
|
|
||
|
|
## Zigduino (atmega128rfa1)
|
||
|
|
|
||
|
|
A basic Zigduino nodes with embedded sensors:
|
||
|
|
|
||
|
|
- [Grove Temperature Humidity sensor](https://wiki.seeedstudio.com/Grove-Temperature_and_Humidity_Sensor_Pro/) (pin 14, A0)
|
||
|
|
- [Grove Light sensor](https://wiki.seeedstudio.com/Sensor_light/) (pin 15, A1)
|
||
|
|
- [Grove Loudness sensor](https://wiki.seeedstudio.com/Grove-Loudness_Sensor/) (pin 16, A2)
|
||
|
|
- [Grove PIR Motion sensor](https://wiki.seeedstudio.com/Grove-PIR_Motion_Sensor/) (pin 4, D4)
|
||
|
|
|
||
|
|
## Zigduino (atmega128rfa1_rn2483)
|
||
|
|
This is an extension of the previous Zigduino (atmega128rfa1)
|
||
|
|
|
||
|
|
- Secondary serial port (LoRa modem): 57600 bauds
|
||
|
|
- [RN2483](https://ww1.microchip.com/downloads/en/DeviceDoc/RN2483-LoRa-Technology-Module-Command-Reference-User-Guide-DS40001784G.pdf) modem with 1.0.3 firmware (LoRaWAN Class A only)
|
||
|
|
- TX (pin 1, TXD1)
|
||
|
|
