Desk of Ladyada - RGB Drivers & CircuitPython Cameras

This week we’ve got a few things we’ve been hacking on. We tested out jepler’s ESP32S2 camera support in CircuitPython. It works really well! Now that we have OV7670 and OV2640 camera modules supported we can move on to designing some hardware. We also wrote up a ISSI IS31FL374x () driver which is a more powerful version of the IS31FL3731 chips what we’ve used for our charlieplex wings. This driver can handle 160 independent RGB LEDs with constant-current adjustment and 8-bit PWM per LED. We would use these for boards that have more than ~50 NeoPixels/Dotstars because ’smart’ LEDs are about 10 cents each on reel. The Great Search - Non-Addressable SMT RGB LED We sure love smart addressable LEDs here at Adafruit - like NeoPixels ( and DotStars ( But our new project is going to us
