Original Gravity: Digital Capacitive Touch Sensor For Arduino – PartsCountry

Description

This development board has a 1.69″ capacitive touch LCD with 240 x 280 resolution and 262K colours that provide vibrant and clear visuals, making it ideal for various projects such as handheld devices, control panels, or portable projects.

Powered by the RP2040 chip, it has dual-core ARM Cortex-M0+ processing with 264KB of SRAM, making it ideal for running custom projects easily. Its compact size and simple connection via USB-C make it easy to integrate into projects, while the included example codes help you get started quickly.

It also includes a lithium battery recharge/discharge header, making it ideal for portable projects, and an onboard RTC chip with a battery header for accurate timing. This module is ideal for anyone looking to add a responsive and colourful display to their projects.

Please note: this board uses a tiny?MX1.25?connector for LiPo power.?Most LiPo batteries on the market (including ours) use a larger JST fitting. We do not yet stock batteries with an MX1.25 connector, however, you can customise your battery with?one of our 1.25mm pitch cables?to make a compatible battery yourself (assuming you have the ability, knowledge and tools to do this safely).
