Precautions:
1. The driver board requires a heatsink and fan for cooling.
2. The driver inputs for this board are LD5V and TEC12V. Terminals J5 and J6 must be connected simultaneously; otherwise, the board will have no output.
3. Input electrodes must not be reversed; otherwise, the board will be damaged.
4. For continuous output, the modulation switch must be set to T-mode.
5. Before use, please adjust the parameters with a load before connecting the laser to avoid damaging the laser.
