The {hardware} choice could be modified however we went with easy-to-get components. One factor to notice right here is that soldering shall be wanted solely to solder headers to the Lilygo TTGO and the BME280 module. This activity could be outsourced to any close by digital store and prevent the cash and the effort.
Meeting
The {hardware} is all prepared and set now to the wiring. For this, we’ll observe the next Schematics.
💡
Please take note we’re assuming right here you already soldered the headers on the board so it will likely be a matter of connecting pins to the fitting place.
BME280 Telemetry Module – Lilygo TTGO
- VCC/VIN -> 5V For BME280-5V OR 3.3V For BMP280-3.3V
- SCL -> PIN 22
- SDA -> PIN 21
- GND -> GND
💡
The BME280-5V Module Would possibly Not Work With a Battery, It Works Solely With USB
💡
When you’ve got a display screen related to the identical ports, Please contemplate connecting the BME280 in parallel mode
💡
Capacitors are good observe for decoupling one a part of a circuit from one other
💡
It is Essential To Notice That The Order Of The Connections Would possibly Range. Comply with The Labels And Io Ports On Your Particular Parts And The Supplied Schematics To Guarantee Correct Wiring. Paying Consideration To These Particulars Ensures That You Set up The Appropriate Connections And Keep away from Potential Points or Damaging Your Parts
As soon as all of the wiring is accomplished. Double-check your connections and guarantee they match the steered format earlier than continuing to the subsequent steps.
