June 17, 20251 yr does orange pi zero2W support the headsets with built in microphone or not? I do not see any MICINN in the 24 pin connector?
June 18, 20251 yr Solution The OrangePi Zero 2w is maintained by the community and chraac in particular. Maybe try to contact him by e-mail if you don't get a response here. Or talk to other owners of the device here in the forum to see if they can answer your question.
June 18, 20251 yr accordingly H618 do not have mic in hardware https://www.cnx-software.com/2023/07/03/orange-pi-zero-3-allwinner-h618-sbc-ships-with-up-to-4gb-ram/ hence, an option is to use a usb soundcard / dongle https://www.aliexpress.com/w/wholesale-usb-sound-card.html there are also those 'arduinoish' approaches e.g. to use a ADC module board e.g. https://www.ti.com/lit/ds/symlink/ads1110.pdf https://www.aliexpress.com/w/wholesale-ads1110.html https://www.instructables.com/Arduino-and-the-TI-ADS1110-16-bit-ADC/ but that you would need to hack the pin interfaces to use i2c etc. note it seemed ads1110 is a bit too slow for sound. alternatives are like stm32, which has built-in adc that can go to like 1-2.5 Msps, but you would need to hack the spi interface etc. the 'easiest / cheapest' way seemed to be generic 'usb sound cards'
