Taiyo Yuden EYSHSNZWZ Bluetooth® V5 Module

Ultra-small Bluetooth® v5 module - EYSHSNZWZ

TAIYO YUDEN’s EYSHSNZWZ is an extremely small Bluetooth® v5 module that incorporates a system clock and an antenna. The module dimensions are only 3.25 × 8.55 × 0.9 mm. 14 GPIOs are supported and it operates on the 2.4 GHz band with +4 dBm of output power. The module would pair nicely with other small form factor sensors requiring minimal space and power. The on-chip processor has sufficient space for many applications, so a carrier board may only include sensors and a battery.
