| Logic power supply (VDD) | 5 V |
|---|---|
| LCD driver voltage (VEE) | Adjustable negative voltage, e.g., –18 V (7918) or –5 V to –26 V |
| Operating temperature range | -10 °C to +35 °C |
| Recommended humidity for operation | ≈60 % RH |
Store the module between –10 °C and +35 °C, in a dark place away from strong light.
The module uses three power supplies: a 5 V logic supply (VDD), a negative LCD‑driver voltage (VEE), and a LED backlight supply of about 3.8 V–4.3 V.
Use a soldering iron temperature below 280 °C and keep each solder joint under 3–4 seconds.
