E22-400M30S

The E22 series products are the first wireless modules in China to adopt Semtech's SX1262 and SX1268 RF chips. This chip provides multiple modulation methods. Meanwhile, the SX126x RF chip has two power distribution methods, a low-dropout regulator (LDO), and a high-efficiency step-down DC-DC converter. On the premise of choosing the DC-DC mode, the received current is extremely low, truly achieving low power consumption.
