Notes

DIY keyboard communicator built around a separate Heltec Wireless Tracker V1.1; the Tracker, switches, headers and assembly are separate. The large OLED configuration uses an optional 18650 holder. The seller has discontinued its assembled big-OLED enclosure bundle. Heltec rates radio output at 21 ± 1 dBm; the comparison value uses the low end of that rating. Select the baseboard and antenna for the intended band. Designed by Peter Misenko (Bobricius).
