WeatherDuino Pro2 PLUS Receiver - Notes about some of the Required Parts
The WeatherDuino Pro2 PLUS is one of the easier boards to assemble ever released. The PCB includes all the SMD parts already welded, and the final user only have to weld a variety of single and double row 2.54mm headers, to connect the display, the local sensors (ATM, Temperature / Humidity) and the microcontroller board.
The parts list to build the Weatherduino Pro2 PLUS unit is published here:

Let's start by the microcontroller. The Pro2 PLUS uses a Meduino Mega2560 Pro-mini board, which includes an ATMEL Mega 2560 microcontroller and a robust USB port. This board can be directly welded on the main board, or installed in a socket. The board is available in two versions: with double pin headers, or double female socket.
The best place to find the Meduino Mega2560 Pro-mini, is on eBay, search by Meduino.
A special note to Australian users: One of the sellers can ship it from Australia, allowing a quick delivery at a slightly lower price.
Regarding the sensors for reading ATM and inside Temperature / Humidity, there is also novelties.
The Pro2 PLUS includes support for the new BOSCH integrated environmental sensor BME280, which combines in just one unit, individual high linearity, high accuracy sensors for pressure, humidity and temperature. However, Pro2 PLUS continues to allow the use of separate sensors for Atmospheric Pressure and home Temperature / Humidity.
Here is the list of supported sensors:
- ATM: BME280, BMP280, BMP180, BMP085.
- Temperature / Humidity: SHT31, SHT21, HTU21D
A very, very important part on all WeatherDuino Pro2 or WeatherDuino Pro2 PLUS units, is the radio modules. The Pro2 PLUS uses the same well tested radio modules, also used on the Pro2 system. Do your best to get exactly the same modules pictured on the parts list, take special care with the receiver module, ensure it is a RXB6 with a 433 mark on the crystal, other very similar modules may work, but most of the times they have a poor performance.
While the Pro2 PLUS keeps the possibility to use an 20x4 LCD display, another of it's interesting novelties is the support for a 2.8" colour TFT display with touch panel. The touch panel is required, as most of the changes between the several screens with data, are done just by touching in the right or left side of the display. The screens with the graphics are accessed by a double click on the push button, that also acts as a switch to turn On of Off the screen backlight, with a single click.
The ILI9341 TFT display used on the Pro2 PLUS base unit, is a well know product, already used in other WeatherDuino units, as is the case of the Wireless Display units.
