Electrical performance parameters
| parameter | Test Conditions | Minimum | Typical value | Max | unit | |
| Operating Voltage① | 4.5 | 5.0 | 6.0 | V | ||
| VCC=5.0V, The maximum backlight brightness | – | 140 | – | mA | ||
| Working current | Normal sleep mode(lowpower=0)② | 4.0 | 4.5 | 5.0 | mA | |
| Deep sleep mode(lowpower=1)② | 0.2 | 0.25 | 0.4 | mA | ||
① Recommended power supply:5.0V 500MA DC power supply
② In this mode, the wake-up time is longer, and some data will be lost when the serial port receives and wakes up. Therefore, it is recommended that customers send an invalid command and delay 50mS Then operate the screen normally.
