Electronic Characteristics
| Test Conditions | Min | Typical | Max | Unit | |
| Operating Voltage | 4.5 | 5.0 | 6.0 | V | |
| Operating Current | VCC=+5V, Brightness is 100% | – | 90 | – | mA |
| Normal SLEEP Mode (lowpower=0) | – | 4.5 | – | mA | |
| Deep SLEEP Mode (lowpower=1) | – | 0.25 | – | mA | |
| 1. Power supply recommend:5V, 500mA, DC. 2. In deep sleep mode, the wake-up time will be longer, the data will be probably lost when the serial port receive is receiving the wake-up command. Therefore, it is recommended to send a void command and delay 50ms before operating. | |||||
