Weather dash
About the Weather dash PCB
Weather dash is an open source PCB design by grimsteel, published on GitHub. It is a 2-layer board measuring 61 × 46 mm, with 11 components from 10 distinct parts.
Other key parts include the WEMOS_S2_MINI and TFT_ST7735_SD. By type, the board carries 3 ICs, 3 switches, 2 connectors, 1 buzzer, 1 diode and 1 resistor.
It belongs with the power & battery and sensors designs in this gallery.
From the project
1.8" weather dashboard - two buttons + rechargable battery + DHT11
- Wemos S2 Mini - 1.8" TFT - DHT11 temp/humidity sensor - Li-ion battery charger
1. ESP32-C3 requires 3.0-3.6V input voltage 2. The LDO technically requires 4.3V for a stable 3.3V, but starts providing 3.0V at an input of ~3.1V 3. The battery is 3.8V 4. The 1N5817 Schottky has a voltage drop of 0.25V at 200 mA 5. Therefore, the LDO will be provided with 3.45V and will output 3.2-3.3V
