LED Panel P10 Fight Timer DMD2 HUB12

Features:

• Training (fight) time count and interval count between trainings.

• • Countdown time.
• • Panel brightness adjustment.
• • Allows user to see date and time while counting (makes automatic return).
• • Automatically return when idle within the menu tree.
• • Audio visual signaling, beep and voice (mp3 files)
• • Independent volume control for beep and voice (player has its volume control).
• • Playing music on USB flash drive and SD card (player also has FM and Bluetooth).
• • Panel operation is independent of mp3 player (shares audio output).
• • Displayed temperature range from 2 to 150 °C (Lower temperature needs different hardware).
• • Battery charge level indication (Controlled by the PN951 power bank).

• Usage temperature up to 45°C maximum due to PN-951 power bank battery.

• Notes:

• • Initially done using remote to learn code (RF 433MHz), but when researching about security, it doesn't seem like a good choice.
• • Researched about the rolling code RF remote control, but it is complicated and the mid-range model with HCSxx is already being considered unsafe. (Search for MCS3142 if you want something safer than the HCS family)
