AZDelivery NodeMCU WiFi Lolin V3 ESP8266 ESP-12F Internet Development Board Modu vs diymore 3PCS ESP32-S3 WiFi Bluetooth Mini Development Board Module Dual-Core Pro

Overview of the AZDelivery NodeMCU and diymore ESP32-S3

The AZDelivery NodeMCU WiFi Lolin V3 is priced at £7.78, while the diymore ESP32-S3 development board trio costs £14.99. This significant price difference highlights the distinct offerings of both products. The NodeMCU is tailored for users seeking a compact, affordable solution for basic WiFi applications, whereas the diymore package provides a more advanced option with additional capabilities.

Performance Comparison

In terms of processing power, the diymore ESP32-S3 boasts a dual-core Xtensa 32-bit LX7 processor that operates at up to 240 MHz. This contrasts sharply with the AZDelivery NodeMCU, which utilises a single-core ESP8266 microcontroller. The additional cores and higher clock speed of the ESP32-S3 likely translate to superior performance for more demanding applications, making it more suitable for complex projects requiring significant processing power.

Connectivity Features

The AZDelivery NodeMCU offers 802.11 b/g/n WLAN support, allowing for reliable WiFi connectivity. Meanwhile, the diymore ESP32-S3 enhances this capability with not only WiFi (also 802.11b/g/n) but also Bluetooth 5.0 (LE). This dual connectivity makes the diymore option more versatile for projects that may require multiple forms of wireless communication, thereby providing a broader range of applications in IoT and smart devices.

Memory and Storage

When examining memory, the diymore ESP32-S3 stands out with its robust specifications, including 512KB SRAM, 384KB ROM, 4MB Flash, and an additional 2MB PSRAM. In contrast, the AZDelivery NodeMCU has a flash memory chip of 4M (32mbit), which is considerably less. This substantial difference in memory indicates that the ESP32-S3 can handle more complex tasks and larger data sets, making it a better choice for advanced projects that require significant memory resources.

Design and Form Factor

The AZDelivery NodeMCU features a compact design with dimensions of 58 mm x 31 mm x 13 mm, which makes it highly portable and easy to integrate into various projects. On the other hand, the diymore ESP32-S3's punch hole design allows for easy integration into custom base plates, although specific dimensions are not provided. The NodeMCU's established compactness is beneficial for users looking to save space in their projects, while the diymore's design flexibility caters to those wanting to create tailored solutions.

Power Efficiency

Power consumption is a key consideration for development boards, particularly in IoT applications where energy efficiency is paramount. The diymore ESP32-S3 offers features like independent module power adjustment and flexible watch modes, which enable low power consumption in various scenarios. The AZDelivery NodeMCU, while efficient, does not explicitly mention advanced power management features, making the ESP32-S3 a more appealing option for battery-operated projects that require optimised power usage.

User Experience and Support

AZDelivery provides an E-Book with the NodeMCU, which includes essential information for project initiation, installation guides, and application examples. This resource can greatly assist beginners in navigating their first projects. The diymore ESP32-S3 does not mention such support materials, which could be a disadvantage for novice users seeking guidance. The included support from AZDelivery may facilitate a smoother learning curve for those new to development boards.

Which should you buy?

Choosing between the AZDelivery NodeMCU WiFi Lolin V3 and the diymore ESP32-S3 ultimately depends on your project requirements. If you are looking for an affordable, compact solution for basic WiFi applications, the NodeMCU is an excellent choice at £7.78. However, for those needing more processing power, advanced connectivity options, and greater memory capacity, the diymore ESP32-S3, despite its higher price of £14.99, offers features that can significantly enhance project capabilities. Thus, weigh your specific needs carefully before making a decision.
