Design a Custom BoardAbout This Component
Ultra-low power sub-1 GHz RF transceiver supporting 413-479 MHz and 826-958 MHz bands with air data rates to 500 kbps. Features -130 dBm receiver sensitivity, 7 mA RX current, programmable output to +16 dBm, and integrated packet handling with FIFO buffers. Ideal for ISM band IoT, smart metering, and wireless sensor networks requiring battery operation and long-range links.
Package: QFN-24 (4×4mm) · 24 pins
Why does this need a breakout?
This 0.5mm pitch QFN is nearly impossible to hand solder and entirely incompatible with breadboards due to hidden pads beneath the package. A breakout board provides accessible headers and pre-soldered connections, letting you prototype with InvenSense motion sensors via I2C or SPI without specialized SMD equipment or rework skills.
