Ivan Holland from CPC has been taking a look at the new PiTalk board from SB Components. The board, which was originally a successful Kickstarter campaign is a 3G-enabled mobile tele-communications solution for your Raspberry Pi. Plugged into the GPIO pins, and with a SIM card added with an appropriate data package, you can trigger actions on your Pi from another phone. Very nifty. With the use of an extended GPIO header, you can piggyback other GPIO boards and HATs and produce versatile projects. Aside from a few issues with the accompanying software, Ivan gives the product a thumbs-up. You can read the full review here.
