Excellent device, support and communication
For AC MAINS Dimmer - MPDMv7.5
I purchased this configuration for a Chandelier project and it works well with:
- 10x6.5W GU10 dimmable LED globes (on/off/dimmming)
It also works well with fluorescent tube lighting (on/off).
The board is designed well and separates the low and high voltage areas. The TRIAC has an insulated tab, which gives more flexibility if you choose to bond a heatsink to it (this is only required if your lighting setup requires it).
This configuration comes with ESP8266 BASIC pre-loaded so you can quickly begin testing your parameter configuration based on your lighting setup. You can of course deploy your own ESP8266 solution (I use Micropython).
The basic MPDM can be adjusted/dimmed with an external voltage controlling device such as a potentiometer or microcontroller solution. By selecting the DAC option, you can achieve integrated stable dimming (the DAC will provide the voltage-based signal for dimming) and by adding the integrated ESP8266 you can control the DAC and implement your own IoT solution - all integrated into one mains powered board.
TJ responded promptly with pre-sales and post-sales questions.
I highly recommended the MPDM device and its associated programming board - which is also electrically isolated.

Relay Impressed,
For AC MAINS Dimmer - MPDMv7.5
it came preloaded with firmware than enabled you to connect to it via wifi and control the Dimmer module, i decided to flash it with a custom version of Tasmota that supported the DAC.
the DAC provided me with smooth dimming. only 1 or 2 slider positions led to a momentary flicker, i used a couple of LED dimmable bulbs, the cheep ones seem to buzz and flicker more so its worth spending the money on that side of things,
Currently have my MPDM setup with Tasmota as an MQTT device on my network, and have Node red switching it on at 1% dim level and increase to 100% over 30 minutes every morning to act as a SAD alarm clock, (Artificial Sunrise Lamp).
Cost wise i think the unit was a little on the high side but i'm happy to pay for the convenience of it being all ready assembled and ready to use. it arrived within 3 days. The build quality looks good and the end results have been worth the investment. still cheaper than buying a off the shelf SAD lamp and with a lot more functionality and control.
Pro's
The power supply is on board
has a mains side fuse.
has pin out locations on the board to aid in adding things to the 8266.
Room for improvement:
Could be worth having a link to the shipped firmware just in case people wanted to go back.
could also be worth a link to custom "DAC compatible tasmota firmware" as could be a time saver for people.
no connector for mains side earth pass though.
Would buy again,
Thanks,
John Cattani
