A picture says more than a thousand words. This is why the world is moving away from text to images and videos. We, as Makers, can profit from this movement because we get dirt cheap hardware to play with. And if it works with an ESP32, even better. Time for a closer look. I am a proud Patreon of GreatScott, Electroboom, Electronoobs, and others. In this video I will: - Compare the features of the four boards - Try to get all of them working. Here we will see that we have to overcome the usual obstacles - Try to use the new class of I2S MEMS microphones presented in my last mailbag. Two of the modules have such a microphone included - Try out two sorts of camera lenses Links: ESP-EYE: http://s.click.aliexpress.com/e/3jk8a0TI ESP-CAM: http://s.click.aliexpress.com/e/pdyJnZgU or http://bit.ly/2Zyo6cc TTGO ESP32 camera Black: http://s.click.aliexpress.com/e/Enh3I63Q or http://bit.ly/2ZpSEMR TTGO ESP32 camera White: http://s.click.aliexpress.com/e/FpeW9hHm or http://bit.ly/2ZkvRCp TTGO T-Journal: http://bit.ly/2ZzlPgV Different cameras http://bit.ly/2ZmJEYV Sketches and overview: https://github.com/SensorsIot/ESP32-Cameras-and-MEMS-Microphones All use the OV2640 camera and some I2S MEMS microphones Supporting Material and Blog Page: http://www.sensorsiot.org/ Github: https://www.github.com/sensorsiot My Patreon Page: https://www.patreon.com/AndreasSpiess My Bitcoin address: 19FSmqbBzb5zsYB1d8Bq4KbxVmezToDNTV If you want to support the channel, please use the links below to start your shopping.
