A shield, in the context of microcontrollers, is an expansion board that can be attached to a microcontroller to extend its capabilities. It serves as a hardware add-on that can provide additional functionality, such as WiFi, GPS, or motor control capabilities, that isn’t built into the microcontroller itself.
Shields are designed to stack onto the microcontroller board, and they usually share the same form factor as the microcontroller to allow for this seamless integration. They can be easily connected and disconnected, allowing users to swap them out based on the requirements of their particular project. These shields can also be designed with built-in components like sensors, drivers, displays, etc., thereby easing the development process and reducing the need for external hardware components.
In summary, a shield is a practical way to expand the abilities of a microcontroller, enabling it to perform tasks or interact with technologies beyond its base capabilities.
In this article, we will dive into some technical details of the Ebyte LoRa E32 module integrated with the STM32 microcontroller. One key feature that we will explore is the WOR (Wake on Radio), which is a significant factor in the world of low-power long-range communication systems.
I want to simplify the use of external SPI flash memory with my Arduino MKR WiFi 1010, therefore, I have created, a simple Shield PCB to achieve my purpose faster.
To help with fast prototyping, I’m going to create a set of shields for the WeMos D1 mini. The shield of this article manages the EBYTE LoRa device (E22, E32 and E220) with HardwareSerial, already exists a variant with SoftwareSerial.
