Big board, requiring one 8-pin, one 14-pin and one other thing: The build is pretty straightforward except for mechanical assembly, and one with an eye towards doing it all in one module with integral chip antenna (http://ww1.microchip.com/downloads/en/DeviceDoc/60001380C.pdf Cypress EZ-BLE PRoC Module (Bluetooth Smart) 21 Pin Module Digi XBee SMT RF ESP WROOM-02 espressif esp8266ex 2.4 GHz Wi-Fi https://www.espressif.com/sites/default/files/documentation/esp32-s2-wroom_esp32-s2-wroom-i_datasheet_en.pdf 2.4 GHz Wi-Fi and Bluetooth combo chip https://www.espressif.com/sites/default/files/documentation/esp32-wroom-32_datasheet_en.pdf Single 2.4 GHz Wi-Fi and Bluetooth combo chip, external antenna, https://www.espressif.com/sites/default/files/documentation/esp32-s3-mini-1_mini-1u_datasheet_en.pdf 2.4 GHz Wi-Fi Bluetooth external antenna espressif 15.4*15.4mm ESP32-S2-WROVER(-I) 2.4 GHz Wi-Fi and Bluetooth combo chip Single 2.4 GHz Wi-Fi and Bluetooth module ESP32-D0WD Espressif ESP32-WROOM-32E 2.4 GHz Wi-Fi and Bluetooth module Single 2.4 GHz Wi-Fi https://www.espressif.com/sites/default/files/documentation/esp32-s2-wroom_esp32-s2-wroom-i_datasheet_en.pdf 2.4 GHz Wi-Fi and Bluetooth module, https://www.espressif.com/sites/default/files/documentation/esp32-wroom-32e_esp32-wroom-32ue_datasheet_en.pdf NINA-B111 LGA module 42 Pin (http://www.ti.com/lit/ds/symlink/ts3l501e.pdf#page=23), generated with kicad-footprint-generator Inductor SMD 1210 (3225 Metric), square (rectangular) end terminal, IPC_7351 nominal with elongated pad for handsoldering.
