Firmware (HEX) and BASIC source code for the Touchscreen Altimeter/Weather Station
Software for the Touchscreen Altimeter, including BASIC source code and a HEX file which includes the Micromite firmware.
Note that this software has been updated (since the article was published) to include the ability to key in QNH pressure updates.
We have also made the original (pre-QNH) source code available for download for readers who are intersted.

DHT22/AM2302 Compatible Temperature and Humidity sensor module
A DHT22/AM2302 or equivalent digital temperature and humidity sensor module, as described in the February 2017 "El Cheapo Electronic Modules" article.
If you're using this to build the Altimeter/Weather Station from December 2017, you will need a 1k resistor wired between pins 1 and 2 and a 100nF capacitor wired in series with pin 4; see errata.

Elecrow 1A/500mA Li-ion/LiPo charger board with USB power pass-through
A 46 x 32mm module with a micro-USB type B input port and a full-size USB type A output port, plus connections for a solar panel and Li-ion/LiPo cell.
For more details, see the article in the August 2017 issue titled "El Cheapo Modules: Li-ion & LiPo Chargers" (starting on page 44).
PLEASE NOTE: the red/black colour coding on the cables supplied MAY NOT match the polarity of the connectors on this module.
Incorporates an onboard step-up circuit to provide a regulated 5V output (at up to 500mA) from the cell, plus a 1A charger and automatic input-to-output pass-through. Supplied with three 2-wire JST 2.0 cables to connect the cell and output and optionally, a solar panel for charging. Also incorporates battery level indicator LEDs.
Note that the input and output USB socket data lines are not connected.
