6-Pack ESP-WROOM-32 Development Board vs Official Raspberry Pi Pico Board

Overview of the Products

In this comparison, we look at the 6-Pack ESP-WROOM-32 Development Board and the Official Raspberry Pi Pico Board. While both are popular choices for developers and hobbyists, they cater to different needs and preferences. The ESP-WROOM-32 is priced at C$45.99 for a pack of six, making it a cost-effective option for those needing multiple units. On the other hand, the Raspberry Pi Pico is an individual board priced at C$12.16, offering versatility and ease of use for various projects.

Design and Form Factor

The design and form factor of these boards significantly impact their usability in different projects. The ESP-WROOM-32 features an ultra-small size of 58 x 28 x 12 mm, allowing for easy embedding into other products. Its compactness suits applications where space is a premium. Conversely, the Raspberry Pi Pico has a slightly larger footprint, measuring 21 mm x 51 mm. While it is still small enough for many applications, its design prioritises a balance between space and functionality, making it suitable for both hobbyist projects and industrial applications.

Processing Power

When it comes to processing power, the two boards take different approaches. The ESP-WROOM-32 is equipped with a Tensilica LX6 Dual Core CPU processor, boasting a calculation speed of 600 DMIPS. This high-performance dual-core capability allows for efficient multitasking and processing of complex tasks. In contrast, the Raspberry Pi Pico features a dual-core Arm Cortex-M0+ processor running at 133 MHz. While it may not match the ESP-WROOM-32's processing speed, the Pico's architecture is designed for low-power applications, making it ideal for projects requiring energy efficiency.

Memory and Storage

Memory and storage capabilities are crucial when selecting a development board. The ESP-WROOM-32 comes with 520 KB of built-in SRAM, providing ample space for running applications and supporting various firmware. This capability is particularly beneficial for IoT applications that require real-time data processing. The Raspberry Pi Pico, however, features 264 KB of on-chip SRAM and includes 2 MB of on-board QSPI Flash. This configuration offers flexibility for storage and programming but may limit more memory-intensive applications compared to the ESP-WROOM-32.

Connectivity Options

Connectivity is a vital aspect of both boards, especially for IoT projects. The ESP-WROOM-32 supports multiple interfaces, including SPI, SDIO, I2C, and UART, making it highly versatile for connecting to various peripherals. Its capabilities support a range of applications, from simple data capture to complex IoT integrations. The Raspberry Pi Pico also offers robust connectivity with 26 GPIO pins, including three analogue inputs and various communication protocols like UART, SPI, and I2C. While both boards excel in connectivity, the ESP-WROOM-32's variety may provide an edge for specific applications.

Power Consumption

Power consumption is an important consideration for developers, especially in battery-powered projects. The ESP-WROOM-32 is designed for low power consumption, making it suitable for long-running applications without frequent recharging. This feature is particularly advantageous for remote IoT devices. The Raspberry Pi Pico also offers low-power sleep and dormant modes, operating within a voltage range of 1.8 to 5.5V DC. While both boards are designed with energy efficiency in mind, the ESP-WROOM-32's focus on low power makes it a strong contender for battery-operated devices.

Development Environment

The ease of development is a crucial factor for many users. The ESP-WROOM-32 supports various firmware, including nodelua, microPython, and FreeRTOS, allowing developers to choose the environment that best suits their project needs. Its compatibility with multiple programming languages enhances its appeal to a broader audience. The Raspberry Pi Pico allows programming in C and MicroPython, providing a user-friendly experience, particularly for beginners. The drag-and-drop programming feature over USB simplifies the development process, making it accessible for users of all skill levels.

Which should you buy?

Ultimately, the choice between the 6-Pack ESP-WROOM-32 Development Board and the Official Raspberry Pi Pico Board depends on your specific project requirements. If you need multiple boards for a cost-effective solution with powerful processing capabilities, the ESP-WROOM-32 is an excellent option at C$45.99 for six units. However, if you're looking for a versatile single board for a variety of applications, the Raspberry Pi Pico at C$12.16 offers great value and ease of use. Consider your project's needs, including processing power, memory, connectivity, and development environment, to make the best decision for your next project.
