Turta Launches Raspberry Pi Modular HAT, Proto HAT Accessories

With six Grove connectors and slots for two of Turta's sensor modules, the Modular Hat is impressive while the Proto HAT is flexible.

Delaware-based Turta has launched a pair of new Raspberry Pi HAT accessories: The Modular HAT, which accepts both Grove-style hardware as well as custom-designed sensor modules from the company itself, and a Proto HAT with on-board analog-to-digital converter (ADC).

"Modular HAT is a sensor connectivity board with two modular sensor slots and six Grove System compatible ports," Turta explains of the first of its two new products. "You can add our modular sensors, which are capable of environmental, ambient light, noise level sensing, and much more with ease. Moreover, external I2C, UART, GPIO, and analog ports are available for external sensor connectivity.

"Two modular sensor slots (with I2C, GPIO, PWM, analog, interrupt); Grove System compatible ports (1x I2C, 1x UART, 2x GPIO, 2x analog); analog-to-digital converter over the SPI CS0; 4Ch single-ended or 2Ch differential analog inputs are available; Board temperature reading on the ADC IC; Stackable Raspberry Pi header; ID EEPROM for Raspberry Pi HAT specification compliance."

The module slots are designed for Turta's own range of compact sensor boards, originally created for the company's IoT Node board, accepting two side-by-side from a range which includes an accelerometer, light and gesture sensing, a button and buzzer, environmental sensing, and even a DIY module with a built-in 7x8 prototyping area for building custom modules.

For those looking to build something more complex than a 7x8 grid would allow, there's the Proto HAT. "Proto HAT is a prototyping board with an onboard analog-to-digital converter for Raspberry Pi," Turta notes. "It has breadboard like pads for IC placement and free pads for everything else. The four-channel analog-to-digital converter is ideal for reading sensor inputs."

More information on the Proto HAT is available on its Tindie product page, where it can be ordered for $9.90; the Modular HAT has its own page, and costs $19.90 with individual modules priced from $6.99.
