| 1: input: DC 4.5 V-7 V (input voltage must be more than to output voltage high 1 V above.). |
| 2: output: 3.3 V, 800 mA (load current can't more than 800 mA). |
| 3: PCB size:8.6* 12.3 mm. |
| Attention. |
| 1: Boost modules or buck module indicate the operating voltage, Please donot exceed operating voltage, or it will be damaged easily . |
| 2: Boost module output voltage can only be greater than or equal to input voltage, cannot be less than the input voltage. |
| 3: Buck module input voltage must be higher than output voltage of 1.5V or 2V, otherwise it can not output enough power. |
| 4: Automatic Adjustable Boost or Buck module has start voltage and limit working voltage, Please donot exceed them, or it will be damaged easily . |
| 5: Cannot reverse polarity, or it will be short circuit, or will be born easily . |
