This is my take on a minimalistic portable mesh node for the RAK19003. Prints with no supports! Battery life is well over a week. Bluetooth companion went from from 90% to 75% in 7 days with several flood adverts and 1-3 messages sent daily.
Battery: Standard size 103450 li-ion with 2mm pitch JST. Remember to check the polarity before plugging in, you can easily swap the wires in the plug if they are wrong. The battery pigtail should be at least as long as the battery.
Radio kit: The intended radio kit is the RAKwireless Mini Meshtastic Starter Kit US915 RAK19003 + 4631 found here: Amazon link.
Hardware: All hardware needed is included in the radio kit.
Firmware: Highly recomend flashing MeshCore from MeshCore.io
There are 3 files:
The outer sleeve that will work with both inner designs.
Insert designs for an external antenna.
Insert design for an internal antenna.
Please print in a material that has good layer adhesion, its only 2 walls. I like PETG, PETG-GF, PET-GF. Avoid using carbon fiber reinforced materials as it may result in some signal attenuation to the internal Bluetooth antenna (untested).
