The CL-32 is a new pocket-sized computer developed by Peter Barker, known as moosepr, featuring an ESP32-S3 microcontroller and an E Ink display. This device is designed to resemble retro pocket computers from the 1980s, offering a modern twist with a 72-key keyboard and a GPIO expansion port. The E Ink display can show 38 lines of text, providing advantages such as lower power consumption and better visibility in sunlight compared to traditional LCDs. The ESP32-S3 operates at 240 MHz and supports Wi-Fi and Bluetooth connectivity. The device is powered by a BP-4L LiPo battery, estimated to last several days on a single charge. While the keyboard layout is still being finalized, it may include a QWERTY-style input and a numeric keypad. The CL-32's GPIO expansion port is designed for durability, making it suitable for educational use. The specific operating environment for the ESP32-S3 is yet to be determined, with possibilities including MicroPython or a custom operating system. Further details about the project are anticipated as it develops.
