| Feb 24, 2023 at 14:27 | comment | added | samkass | I have been considering the AdaFruit Huzzah32 Feather ESP32… 16 analog inputs (2 DACs); built-in Wi-Fi, Bluetooth and USB; LiPo battery source/charger built-in; and compatible with Arduino IDE, all for $20. (WipperSnapper IoT compatible.) Seems like this part might satisfy the original question. | |

All of those pins are exposed in the pinout picture from TheHookUp's guide. I don't trust 100% those tutorials on the internet. It is good in its own context but sometime wrong in different context. | |
| Jan 29, 2021 at 14:17 | comment | added | Brian Yap | Based on this chart github.com/thehookup/ESP32_Ceiling_Light/blob/master/… , it looks like the NodeMCU ESP32 only has 6 analog input pins. Am I misunderstanding something? | |

Adjust into short answer.

| Jan 29, 2021 at 3:05 | comment | added | SimonVu14 | To StarCat, can you read the pinout picture? OP wants something that doesn't cost much, has plenty of ADC channel and works out of the box without extra addon. Are you trying to say, I have to give answer on strictly arduino board from arduino.cc only? I edit my answer to just answer what OP wants as in the question. | |
| Jan 29, 2021 at 2:38 | comment | added | SimonVu14 | To hcheung, I don't have much experience with ESP32's ADC, but if I want low noise ADC, I rather roll external ADC with it's dedicated low noise PSU. I've been using ADC from a few Arm M0/M0+, not really happy with them. | |

| Jan 29, 2021 at 0:08 | comment | added | hcheung | OP is looking for interfacing with a lot of analog sensor. ESP-32 won't be a good choice if you want to use ADC, it is noisy, non-linear... | |
| Jan 28, 2021 at 16:47 | comment | added | StarCat | One of the issues in the question was the number of analog ports available. You did not mention them in your answer. | |
| Jan 28, 2021 at 16:37 | comment | added | Juraj♦ | the WiFi module on Nano 33 IoT is an ESP32 | |
| Jan 28, 2021 at 16:06 | comment | added | xbox gamer | According to me this almost answers the whole question except why is it cheaper . | |
| Jan 28, 2021 at 15:56 | comment | added | StarCat | Could you explain how this answers the question? | |
