ESP32 pla­nars come dime a dozen. We will use the DEVKIT C, which is con­ve­niently avail­able from https://www. elek­tor.com/esp32-de­vk­itc. First, make sure that all rel­e­vant drivers are in­stalled and that the se­rial port be­comes vis­i­ble. As we work on Linux, we ex­pect it to mount at /dev/ttyusb0. Open a re­cent Ar­duino IDE (>=1.8), and use the board man­ager to in­stall an ESP32 core ac­cord­ing to the steps out­lined at https://github.com/ es­pres­sif/ar­duino-esp32/blob/ mas­ter/docs/ar­duino-ide/ board­s_­man­ager.md. Next, open the Board choice tool and se­lect “ESP32 Dev Mod­ule”. Fi­nally, use the Tools menu to se­lect the cor­rect se­rial port. When setup is com­plete, de­ploy a sketch of choice – if the pro­gram­ming process suc­ceeds, all is well.
