The board came in excellent condition. The GPIO headers were undamaged, protected with foam and came pre-soldered with pins. I was able to easily flash the Micropython ESP32 generic firmware onto it. Extremely VFM as compared to other mainstream e-commerce platforms.
All great but too late delivery
very bed
Working great.
ok good product resived working well
I bought the 38-pin Type-C CP2102 board for a WLED project. It works flawlessly, though it gets a bit warm during Wi-Fi usage. Despite missing the Espressif logo on the metal shield, the chip is 100% genuine and officially manufactured by Espressif.
nice
"I recently bought this ESP32-WROOM development board, and it works perfectly. The build quality is excellent. Both Wi-Fi and Bluetooth connect very quickly without any issues. I used it for a smart home automation project, and the dual-core processor delivers amazing speed. It is fully compatible with Arduino IDE, making programming very easy. For this price range, it is definitely a value-for-money product. 5/5 stars from my side!"
it works good
Very good quality. Product is working properly. Delivery is a little slow, but ok! Price is lower than Amazon, Flipkart, etc, but higher than local market.
Overall good !!
