 The [Heltec HTCC-AB01 (V2) ](https://heltec.org/project/htcc-ab01-v2/) is a development board based on the ASR6052, which has an integrated PSoC® 4000 series MCU (ARM® Cortex® M0+ Core) and SX1262 transceiver. It features Arduino compatibility, an ultra low power design and an onboard SH1.25 for lithium batteries or solar panels.

 Then go to the **Tools** menu and you will see a couple of options. Let's run through the important ones that you have to check:
 
-- **LORAWAN_CLASS** – For now, we will use Class A (for more info check [here](https://www.thethingsnetwork.org/docs/lorawan/classes/)).
-- **LORAWAN_DEVEUI** – Select `Generate by ChipID`, which generates based on the ASR650x's unique Chip ID.
-- **LORAWAN_NETMODE** – Make sure it has `OTAA` selected.
