I recently came across SODAQ (SOlar Data AcQuisition), an interesting Arduino-based board that promises to make IoT prototyping faster and easier.
What do you need for an IoT project? A microcontroller platform, some sensors and actuators, power and of course a wireless interface. SODAQ provides all these in one board, featuring Grove sensor interfaces and a xBee socket.In addition, there two power connectors, one for a rechargeable battery and one for a solar panel (hence the name). These mean basically two things:
1) You can easily add any Grove compatible (and Seeedstudio provides a huge list!) sensor or actuator by simply plugging it on the board. No needs for soldering or ‘breadboarding’.
2) You can select the best wireless interface that suits your projects (RF, Bluetooth, WiFi, GPRS).
The board is quite small and compact, it is the size of a RaspberryPi, so any Pi-case can do for SODAQ too. People behind SODAQ claim that it draws about 100 times less power than a Pi to connect your things.
SODAQ comes with the following specs:
- Atmega Microcontroller running at 3.3V and 8MHz
- Arduino Compatible
- Power supply by LiPo battery (3.7V) or USB cable
- Solar charge controller with JST connector for Solar Panel up to 2.5W
- Battery Monitor
- DS3231 Real Time Clock and Temperature sensor, clock backup powered by LiPo battery
- 8 MBit data flash module (AT45DB)
- Micro USB connector
- 12 Grove connectors connecting Digital, Analog and I2C pins
- On/Off switch. With the switch in Off position the solar charge circuit is still active and the RTC clock is still powered.
- ICSP programming header
- Bee socket for Xbee, GPRSbee or other bee style modules
- Same size as Raspberry Pi
The board is open source and looks very promising! Wish I can have one soon to build my next project! You can order yours here.
