Overview of ESP32 Chip

ESP32 is a single chip 2.4 GHz Wi-Fi and Bluetooth combo chip designed with TSMC ultra low power 40 nm technology. It is designed and optimized for the best power performance, RF performance, robustness, versatility, features and reliability, for a wide variety of applications, and different power profiles.
ESP32 is the most integrated solution for Wi-Fi + Bluetooth applications in the industry with less than 10 external components. ESP32 integrates the antenna switch, RF balun, power amplifier, low noise receive amplifier, filters, and power management modules. As such, the entire solution occupies minimal Printed Circuit Board (PCB) area.
ESP32 is designed for mobile, wearable electronics, and Internet of Things (IoT) applications. It has many features of the state-of-the-art low power chips, including fine resolution clock gating, power modes, and dynamic power scaling.

1 review for ESP32 Development Board – Developer Edition

  1. 5 out of 5

    (verified owner)

    Received after a month to Sweden. Very good packed in tiny paper cartoon. Supplier very good and positive in communication.

    PROS:-
    ESP32 is long awaited big bang in wireless IoT Things with bunch of features packed into same form factor as its predecessor ESP8266. More importantly its feature of putting into ultra low power Deep sleep and waking up again with WiFi ready to go, no need to do hard reset a problem troubled ESP8266 users.

    This ESP Wroom-32 dev board gave a good first impression and looks good quality, worked perfectly in first run. I ordered board without headers and soldered headers by myself. Windows 8.1 PC detected the CP2102 USB-TTL serial chip without asking for any drivers. Followed procedure of setting up as per https://github.com/espressif/arduino-esp32 There were some glitches but managed set it UP and running in few minutes. I will post video tutorial soon on my channel https://www.youtube.com/channel/UChjgqHTZ41qw2-dT_3MjdHg/videos

    CONS:-
    One issue in this board is it did not had any LED connected to GPIO pins other than one green color LED that is continuously ON when board is powered UP. I had to connect external LED to check if i could play with GPIOs. But on the contrary, not having any LED onGPIO is also good because this leaves all GPIOs for us to utilize in actual applications.

    Another thing i didn’t like is the Antenna protruding out of the main PCB board. May be this is done on purpose to enhance its range, but not sure. Since, It is thin and looks delicate, I am afraid of breaking it during handling. Because, I was used to NodeMCU board where antenna has been well supported by base PCB.

    Lastly, after some time of operation I noticed strange smell coming out from board, as if something is burning or very hot. I found that with normal wifi sketch running, the 3.3V voltage regulator is quite warm (not very HOT) and so is the actual ESP32 metallic case. This was not the case for ESP8266 (NodeMCU boards).

    Nevertheless, neglecting these minor non-serious CONs, the board worked perfectly and is doing its job well and good. I am eager to play with it more and put to some serious use.
