JT-2850-8 is an 8-channel, ultra-low power consumption, read-write module that supports EPC C1 G2/ISO 18000-6C protocol. With a 40x40mm ceramic antenna, it can read ordinary white cards, and each antenna can achieve a measured width of 60-80cm.

Product features:

Ultra low rate output, maximum RF power is 17dBm

Ultra low power consumption, maximum operating current: 120mA

Supports two-way UART communication, one for RS485 output and the other for RS232 output

Provide SDK development packages that support multiple development languages, making it easy for users to develop again
