MMDVM hotspot with built-in power bank for portable operations
Description
This is the working prototype of the MMDVM hotspot integrated with 5200mAh power bank in a single case. The DV module with SMA antenna is not best choice for that project, but since I do not own module with built-in antenna I used what I have so far. Actually all elements of the enclosure do not have any allowances as it planned to be used on a bicycle and no rattling is allowed there, therefore if you decide to print it out right away, depending on material used, for better fit get ready to perform some manual sanding. On purpose to reduce power consumption, the MMDVM module does not have display on it, but external OLED or Nextion display can be connected to the corresponding pins available on the board while device is powered by the wall charger. Parts and modules: - Dual Micro USB 18650 Lithium Li-ion Battery Charger Module 5V 1A 2.1A - Pair of 18650 Lithium Li-ion Batteries, 3.7V - MMDVM Simplex - Raspberry Pi Zero W
