ESP32 WROOM-32D ESP32-DevKitC V4 wifi Bluetooth ESP32 Development Board Module
ESP32-WROOM-32D ESP32-DevKitC V4 wifi ESP32 Development Board Module
If you are interested in connecting your project to the Web and being a part of the IOT (Internet of Things) project, this development board is for you! Like other microcontrollers and microprocessors, the ESP32 is built in power regulation circuits, on-board antennas, noise filters, and fits snugly on any breadboard for rapid prototyping.
The ESP32 can interface with other MCUs as a master or slave, or operate completely independently via SPI / SDIO, I2C and UART. The microcontroller can also support multiple sensors with an SD card and 32 GPIO pins (all available for PWM).
ESP32-WROOM-32D is a powerful, generic Wi-Fi+BT+BLE MCU modules that target a wide variety of applications, ranging from low-power sensor networks to the most demanding tasks, such as voice encoding, music streaming and MP3 decoding.

Why a Raspberry Pi Pico?
Designing your own microcontroller instead of buying an existing one brings a number of advantages. According to Raspberry Pi itself, not one of the existing products available for this comes close to their price/performance ratio.
This Raspberry Pi Pico has also given Raspberry Pi the ability to add some innovative and powerful features of their own. These features are not available anywhere else.
A third reason is that the Raspberry Pi Pico has given Raspberry Pi the ability to create powerful software around the product. Surrounding this software stack is an extensive documentation set. The software and documentation meet the high standard of Raspberry Pi's core products (such as the Raspberry Pi 400, Pi 4 Model B and Pi 3 Model A+).
Who is this microcontroller for?
The Raspberry Pi Pico is suitable for both advanced and novice users. From controlling a display to controlling many different devices that you use every day. Automating everyday operations is made possible by this technology.
Beginner users
The Raspberry Pi Pico is programmable in the C and MicroPython languages and is customizable for a wide range of devices. In addition, the Pico is as easy to use as dragging and dropping files. This makes this microcontroller ideally suited for the novice user.
Advanced users
For advanced users, it is possible to take advantage of the Pico's extensive peripherals. The peripherals include the SPI, I²C, and eight programmable I/O (PIO)-state machines.
What makes the Raspberry Pi Pico unique?
What's unique about the Pico is that it was developed by Raspberry Pi itself. The RP2040 features a dual-core Arm Cortex-M0+ processor with 264 KB of internal RAM and support for up to 16 MB of off-chip Flash.
The Raspberry Pi Pico is unique for several reasons:
The product has the highest price/quality ratio in the microcontroller board market.
