loPy

loPy is a low-power wireless microcontroller board designed and produced by Pycom, a company specializing in IoT (Internet of Things) devices. First released in 2017, the loPy is a compact, low-cost solution for wireless connectivity applications.

The board features a 64 MHz ESP32 dual-core processor, Wi-Fi, and Bluetooth Low Energy (BLE) wireless connectivity. It is powered by a Li-Polymer battery and can run for up to 3 years on a single charge, depending on usage. Weighing just 6.3 grams, the loPy is an extremely compact device, making it ideal for wearables, sensor nodes, and other applications where size and power consumption are critical factors.

One of the key features of the loPy is its ability to maintain a connection to a base station even if the device itself is moved around or experiences varying levels of connectivity. This is known as LWM2M (Lightweight Machine-to-Machine) support, which allows the device to always be reachable and secure.

The loPy also supports a wide range of programming languages, including MicroPython, a lightweight Python implementation that is ideal for resource-constrained devices. This allows developers to easily write and deploy applications on the loPy, making it an attractive option for those looking to develop IoT projects.

Overall, the loPy offers a unique combination of low power, wireless connectivity, and compact design, making it a popular choice for various IoT applications.

The device is also supported by a large community of developers and makers, with many projects and tutorials available online to get started.
