Do you need ‘moar power’ for your wireless widget? The XBee-PRO XSC 900 MHz RF module features two times the throughput and 20 times less current draw than the previous XSC module. This version (S3B) features an ADF7023 transceiver from Analog Devices, which can toss your data up to 28 miles Line-of-Sight (LOS), along with low power consumption, drawing less than 2.5 uA in power down.
