Teensy wifi weather logger: common questions
What microcontroller does the Teensy wifi weather logger use?
The Teensy wifi weather logger is built around the ESP-01v090, from the ESP8266 family.
How big is the Teensy wifi weather logger PCB?
The Teensy wifi weather logger measures 3.6 × 3.6 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Teensy wifi weather logger?
11 components, from 11 distinct parts. The full bill of materials is listed on this page.
Where can I download the Teensy wifi weather logger design files?
From the pdp7/teensy-wifi-weather-logger repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Teensy wifi weather logger design in my own project?
Yes, under the terms of its CERN-OHL-1.2 license, which pdp7 chose for the repository.
Can I test firmware for the Teensy wifi weather logger without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP8266 firmware against it before you order a PCB.
