Stackable Raspberry Pi add-on has four switched relays
Sequent Microsystems has launched a $20 “4-Relay” add-on for the Raspberry Pi with four line-switching relays for loads of up to 10A and 250V. The cards can stack up to 8x high for 32 switched relays.
Sequent Microsystems has won Kickstarter funding for a Raspberry Pi add-on card designed to switch multiple lights or appliances. Unlike Sequent’s earlier Raspberry Pi 8-Relay Card, which can stack 8x high for 64 relays, the new 4-Relay card offers switching capability between the relays, with support for up to 10A and 250V loads on each relay.
