The Wemos D1 mini

We have seen that the ESP01 can be programmed with micro Python and that there are add-on sensor boards available. However, when we connect the sensor board we loose the serial connection to the PC. This can be corrected by soldering extra connectors to the top of the ESP01 board but this is fiddly and needs good soldering equipment and good soldering skills.

A better and only slightly more expensive solution (we are talking about ~ 3.5 US$ instead of 2.5 US$) is the Wemos D1 mini board.

This module comes with 4 MBytes of flash (as compared with 1 MByte for the ESP01) it has 16 external pins and it features a micro USB connector. Several sensor/actuator boards are available for this board which can be easily stacked together with a base board.

Here is a selection of some of the sensor and actuator boards.

This is the hardware solution chosen for the AFNOG-2019 workshop.
