<p class="mw-empty-elt"></p><p>The <b>Heltec HT-RA62</b> is a <a href="https://en.wikipedia.org/wiki/LoRa" class="extiw external" title="wikipedia:LoRa">LoRa</a> <a href="https://en.wikipedia.org/wiki/RF_module" class="extiw external" title="wikipedia:RF module">module</a> based around the SX1262 LoRa <a href="https://en.wikipedia.org/wiki/Transceiver" class="extiw external" title="wikipedia:Transceiver">transceiver</a> chip. It is one of the main components of the <a href="FakeTec" title="FakeTec">fakeTec</a>.

<div class="mw-heading mw-heading2"><h2 id="Models">Models</h2></div>

<p>There are two models of the HT-RA62. The <em>HT-RA62-HF</em> operates on frequencies between 863 and 928 MHz, while the <em>HT-RA62-LF</em> operates on the lower-frequency 433 and 470 MHz band.

</p>

<div class="mw-heading mw-heading2"><h2 id="Clones">Clones</h2></div>

<p>There are several pin-compatible clones of the HT-RA62, including the RA-01SH. Some of these clones lack the precise <a href="https://en.wikipedia.org/wiki/TCXO" class="extiw external" title="wikipedia:TCXO">TCXO</a> of the original, causing issues when operating at a low <a href="LoRa_parameters#Bandwidth" title="LoRa parameters">bandwidth</a> setting.
