Toby’s top HAT specification interconnection solutions

We are proud to stock Samtec surface mount connectors and through-board sockets, specified for Raspberry Pi HAT (Hardware Attached on Top) applications. Taking advantage of the 40-pin GPIO header, Raspberry Pi HAT specification enables automatic identification and configuration of the GPIOs and drivers for RPI add-on boards. Toby stock these connectors as standard to support this user-friendly approach to board design and development for the Raspberry Pi.

At the outset Toby worked very closely with Samtec and the RPI Foundation to achieve the foundations desire for a cost-effective, off the shelf solution specifically for designers of HAT-compliant boards. Since the initial design in 2014 Toby have maintained the low pricing and stock availability of the “REF” HAT spec series, supporting the worldwide maker community and industrial users alike.

Toby’s comprehensive range of HAT spec connectors include, flush low profile solutions as well as longer tailed, extended pass through options.

The SMT bottom entry sockets can be soldered to the top of a HAT-compliant add-on board and are available either with (REF-182665-01) or without (REF-182665-03) locating pegs. Using Samtec’s Tiger Beam™ contact technology, these sockets allow excellent pass through connection and reliability.

The Samtec sockets, which mate the Raspberry Pi’s GPIO to the connector on the add-on board, are available with either 4.93mm pins for a flush finish (REF-182683-02), longer 10mm pins (REF-182684-02) or even longer 14.83mm pins (REF-187026-03). The extended tail sockets are available in standard insertion force (SIF) and low insertion force (LIF) mating options. All have square tail pins to provide further board stacking interconnect options.

All parts can be ordered online, with no intrusive minimum order quantity or minimum order value. Needless to say whatever your intended HAT application, you can cap it with Toby.
