Sixteen Universal Analog/Digital Inputs HAT Launched by Sequent Microsystems

 In the rapidly evolving world of Raspberry Pi technology, Sequent Microsystems has taken a bold step forward with their latest creation: the Sixteen Universal Analog/Digital Inputs HAT. This innovative hardware accessory is designed to bridge the gap between the computing prowess of the Raspberry Pi 5 and its limitations in handling analog and digital signals. Let's dive into the features and capabilities that make this HAT a game-changer for Raspberry Pi enthusiasts.

Connecting Raspberry Pi to the Real World: The Need for the Sixteen Universal Inputs HAT

As Raspberry Pi 5 made its entrance with impressive computing power, Sequent Microsystems' Mihai Beffa recognized a crucial limitation. Despite being three times faster than its predecessors, the Raspberry Pi 5 struggled with processing analog and digital signals effectively. In response, Sequent Microsystems developed the Sixteen UniversalInputs HAT to connect the Raspberry Pi to the "Real World," adding support for up to 128 analog or digital inputs.

Unveiling the Stackable Power: 128 Universal Inputs at Your Fingertips

The claim of supporting 128 "universal inputs" is not just a boast. Each individual board of the HAT supports 16 inputs, and these boards can be stacked up to eight tall. When you include the Raspberry Pi at the base, the total reaches an impressive 128 inputs. These inputs can be configured for analog or digital signals, accommodating a variety of devices such as thermistors, dry-contact inputs, counters, and 0-10V analog signals, all with a rapid sampling rate of 500Hz.

Versatility in Integration: Compatibility Beyond Raspberry Pi 5

The Sixteen Universal Inputs HAT is not limited to the Raspberry Pi 5; it can be used seamlessly with any Raspberry Pi model or in stand-alone mode. Its versatility extends to integration with standard Programmable Logic Controllers (PLCs) through MODBUS connectivity. Moreover, Sequent Microsystems offers nine other HATs with an identical form factor, allowing them to be stacked along with the Sixteen Inputs for even more expanded capabilities.

Technical Marvels: Features that Set the HAT Apart

The HAT connects to the Raspberry Pi through the I2C bus, leaving the GPIO pins free for other applications. Each board boasts RS485 input and output ports, a real-time clock with battery backup, a hardware watchdog, a resettable fuse, and a dedicated 32-bit processor running at 64MHz. Additionally, DIP switches provide a user-friendly configuration alternative to traditional jumpers.

Join the Revolution: Kickstarter Campaign and Rewards

Excitingly, the Sixteen Inputs HAT is currently seeking support on Kickstarter, with backers gaining access to physical rewards starting at $59. This offers a compelling 15 percent discount over the eventual retail price. The anticipated shipping of these revolutionary HATs is set to commence in February of this year. Sequent Microsystems has once again proven its commitment to innovation, making this HAT a must-have for Raspberry Pi enthusiasts and electronic hobbyists alike.
