The E70 series modules are operating at the center frequency 433MHz,868MHz and 915MHz as options. It is based on the CC1310 originally imported from TI, with TTL level output,3.3V IO port voltage, and a 24MHz industrial high-precision low-temperature drift crystal oscillator; ensuring its industrial capability and stability.
The module has a FEC (Forward Error Correction) algorithm, which ensures its high coding efficiency and good correction performance. In the event of burst interference, it can actively correct interfered data packets, thereby appropriately increasing reliability and transmission range. But without FEC, these packets can only be discarded.
The factory has built-in low-power multi-function wireless serial firmware, users can also carry out secondary development according to the needs.
