In this update: - [PRO] Updated the database of SMD components’ markings. It now stores 518 thousand components and is available without Internet access. - Updated ESP32 pinouts. - Capacitor code calculator now additionally displays calculated capacitance with milli, micro, nano and pico prefixes. - Improved contrast of some elements when a dark color scheme is used. Big thank you to everybody who subscribed or purchased the app's PRO version. Your support helps to make this app even better. If you like this app, please rate it and leave a review.
