Heltec Wireless Stick Lite, OLED 1.3" & GPS case
Description
PDFCase for the combination of Heltec Wireless Stick Lite v3, 1.3" OLED display and GPS, ideal for your APRS tracker device.
The case is also designed for two 18650 Li-Ion batteries, which will power your device. In order to be able to switch pages on the display, there is space for a 6x6 mm button on the front of the case. The middle part is also available with a hole for this switch.
Four M3x20 mm screws are also needed to connect the entire case. Two printed OLED holders and one GPS holder are used to attach the display and GPS antenna. The button cover should hold when pushed into the hole, but you can still drip it with super glue.
