ESP32-S3 Rotary Encoder: LILYGO T-Encoder-Pro
Introduction:
The LILYGO T-Encoder-Pro is a small but powerful device that many tech lovers and developers might find interesting. It is built around the MCU ESP32-S3 R8, which is known for its strong performance and capabilities. This MCU is at the heart of the device and makes it possible to run various applications smoothly.
LILYGO T-Encoder-Pro Memory Capacity
The LILYGO T-Encoder-Pro comes with a generous amount of memory. It has 16MB of Flash memory, which is important for storing data and applications. In addition, it has 8MB of PSRAM. PSRAM stands for Pseudo-Static Random-Access Memory, which helps in handling more complex tasks and improves the overall performance of the device.
Wireless Capabilities in LILYGO T-Encoder-Pro
One of the standout features of the LILYGO T-Encoder-Pro is its wireless capabilities. It supports 2.4 GHz Wi-Fi, which allows the device to connect to the internet. This is useful for many applications, from sending data to receiving updates. It also has Bluetooth 5 (LE), a modern version of Bluetooth that is energy-efficient and fast. This means you can connect the T-Encoder-Pro to other devices like smartphones, tablets, or computers without using too much power.
LILYGO T-Encoder-Pro Onboard Functions
The device has several onboard functions that make it flexible. One notable function is the buzzer, which is connected to PIN IO17. This buzzer can be used to create sound alerts or notifications. Additionally, there are two Qwiic 4-Pin connectors. These connectors make it easy to add more components to the T-Encoder-Pro, increasing its functionality without needing to solder or use complex wiring.
LILYGO T-Encoder-Pro High-Resolution AMOLED Display
A key feature of the T-Encoder-Pro is its display. It boasts a 1.2-inch AMOLED screen with a resolution of 390 x 390 pixels. AMOLED stands for Active Matrix Organic Light Emitting Diodes, which is a type of screen technology that produces bright and vivid colors. This high-resolution display is driven by the SH8601A-W14-T06 chip, which uses the QSPI bus protocol to communicate with the rest of the device. QSPI, or Quad Serial Peripheral Interface, allows for fast data transfer between the display and the MCU.
LILYGO T-Encoder-Pro Touch and Rotary Encoder
Another interesting feature is the CHSC5816 touch and rotary encoder. This component allows for both touch input and rotation input. The touch input uses the I2C protocol, which is a simple and efficient way to communicate between components. The rotary encoder allows you to rotate left and right, which can be used for scrolling through menus or adjusting settings. This combination of touch and rotation input makes the T-Encoder-Pro very user-friendly and flexible.
Size of LILYGO T-Encoder-Pro
In terms of size, the T-Encoder-Pro is compact, measuring just 43.5 by 27.5mm. This small size makes it easy to integrate into various projects without taking up too much space. Although it is small in size, it is packed with features and capabilities.
LILYGO T-Encoder-Pro USB Charging
The T-Encoder-Pro also supports USB charging. It uses a 5V 500mA charger, which is a common and convenient way to power the device. This means you can charge it using a standard USB charger, making it easy to keep the device powered and ready to use.
Conclusion:
In summary, the LILYGO T-Encoder-Pro is a small but powerful device with many features that make it suitable for different applications. It is built around the ESP32-S3 R8 MCU, which provides strong performance. It has plenty of memory with 16MB of Flash and 8MB of PSRAM. The device supports 2.4 GHz Wi-Fi and Bluetooth 5 (LE), allowing it to connect to the internet and other devices easily. It has onboard functions like a buzzer and Qwiic connectors, making it flexible and expandable. The 1.2-inch AMOLED display with a high resolution provides a clear and bright interface, driven by the SH8601A-W14-T06 chip using the QSPI protocol. The CHSC5816 touch and rotary encoder add intuitive input options, using the I2C protocol for touch and allowing rotation for easy control. The compact size of 43.5 by 27.5mm makes it easy to fit into many projects, and the USB charging support ensures it is always ready to go. Overall, the T-Encoder-Pro is a great choice for anyone looking for a powerful, versatile, and compact device.
