20 pin header for FLEX RF Module (Flex RF Module sold separately)
Breadboard style 70 thru hole prototyping area allows you to add you own sensors or actuators and connect to the FLEX RF module
The prototyping area has +VE and GND rails down the center and 6 rows perpendicular of 5 connected thru holes
Power options are 1.5V, 3.3V and 5V through three different power converters:
1.5V to 3.3V converts 1.5V from the on board AA battery to 3.3V required for the FLEX RF Module, or
5V to 3.3V converts 5V from the on board mini USB port to 3.3V required for the FLEX RF module. You need an external power supply via a USB cable for this option (e.g. an old phone charger)
1.5V to 5V (sold separately) converts 1.5V to 5V for any sensors that require 5V. This converter will only supply the prototyping area, so you will also need the 1.5V to 3.3V converter to power the FLEX RF Module
The power rail voltage is set by bridging one of three SMD pads between the 10 pin RF module header (see picture for more details)
Conveniently attach a DHT22 (temperature and humidity sensor) or DS18B20 digital temperature sensor (both supported by the FLEX RF module) without any additional wiring
The PCB is mounted in the case via two supplied screws
The elegant cream colored case
The case has vents to allow for environment monitoring (temperature humidity
Case dimensions 2.91"(74mm) x 2.16"(55mm) x 1.10"(28mm)
The FLEX RF module will run for years on a single AA battery when in deep sleep mode. When the module is fully awake then it will last a few days on a AA battery. See section 14 of the manual for more details.
