2.1 Ihe achọrọ
Iji mepụta ngwa maka modul ị ga-achọ:
- 1 x ESP32-WROOM-DA modul
- 1 x Espressif RF bọọdụ nnwale
- 1 x USB-na-Serial bọọdụ

Na ntuziaka onye ọrụ a, anyị na-ewere sistemụ arụmọrụ Linux dị ka example. Maka ozi ndị ọzọ gbasara nhazi na Windows na macOS, biko rụtụ aka na ESP-IDF Programming Guide.
2.2 Njikọ Hardware
- Solder modul ESP32-WROOM-DA na bọọdụ nnwale RF dị ka egosiri na eserese 2.
Ọgụgụ 2: Njikọ ngwaike - Jikọọ bọọdụ nnwale RF na bọọdụ USB-na-Serial site na TXD, RXD, na GND.
- Jikọọ eriri USB-na-Serial na PC.
- Jikọọ bọọdụ nnwale RF na PC ma ọ bụ ihe nkwụnye ọkụ iji mee ka ọkụ 5 V dị ike, site na eriri Micro-USB.
- Mgbe nbudata, jikọọ IO0 na GND site na jumper. Mgbe ahụ, gbanye "ON" osisi ule.
- Budata firmware n'ime flash. Maka nkọwa, lee akụkụ ndị dị n'okpuru.
- Mgbe nbudata, wepụ jumper na IO0 na GND.
- Kwado bọọdụ nnwale RF ọzọ. ESP32-WROOM-DA ga-agbanwe gaa na ọnọdụ ọrụ. Ihe mgbawa ga-agụ mmemme site na ọkụ mgbe mmalite.
