AstraControlPower
4 Channel LED Driver with PWM dimming input. LED2001PHR is the driver IC, it can support up to 4A, 3V - 18V at 850KHz switching frequency. Test plugs for each input and output. Optimized for good dimming performance. The board connects to AstraControl ESP32-based control PCB uses WiFi with an external antenna and 5Mbps RS-485. Direct copper heat-sink PCB for LED diode AstraBeamLED.

Solder paste stats:
Using a paste with 87.75 % alloy, that has an specific gravity for the alloy of 7.4 g/cm³ and 1.0 g/cm³ for the flux. This paste has an specific gravity of 4.15 g/cm³.
The stencil thickness is 0.12 mm.
| Side | Pads with paste | Area [mm²] | Paste [g] |
|---|---|---|---|
| Total | 2 | 3.48 | 0.02 |
Note: this is just an approximation to the theoretical value. Margins of the solder mask and waste aren’t computed.
