Product of the day: our carriers for @allegromicro's ACS37041/ACS37042 ICs are great, low-cost, galvanically isolated current sensors that are available in different form factors (0.3″×0.4″ micro and 0.7″×0.8″ compact), ranges (±10A and ±30A), and logic voltages (3.3V and 5V). Compared to the ACS37041, the ACS37042 offers a higher isolation voltage rating, and we have added slots to the PCBs to increase the creepage distance up to 2mm and 3mm for the micro and compact carriers, respectively. Today we are highlighting the 5V, ±10A ACS37042KLHBLT-010B5 micro version, on sale for $3.75! pololu.com/product/5452?coup…

Product of the day: our carrier boards for @TXInstruments ISO654x series of 4-channel digital isolators enable digital communication between two electrically isolated devices at up to 50 Mbps per channel. This means that current cannot flow from one side to the other, and incorrect connections or bad voltages on one side cannot propagate through to damage the other. Plus, the logic voltage can be at different levels on both sides, allowing these boards to function as level shifters. Snag some today for $2.25! pololu.com/category/379/iso6…
