Introduction 1.1 Feature E70(915T30S) is wireless UART transceiver module based on the original CC1310 of TI, operating at 907~922.5MHz (Default: 915MHz), TTL level and 3.3V IO port. The module has the function of data encryption & compression. The data of the module transmitted over the features randomness. With the rigorous encryption & decryption, data interception becomes pointless. The function of data compression decreases the transmission time & probability of being interfered, while improving the reliability & transmission efficiency.

Perfectly realize continuous transmission for the highest baud rate of 115200bps. Air data rate, FEC and Encryption are configurable by users;
Transmitting data to the receiver in present air data rate with a most effective way to realize low delay and high respond. The receiving current is 14mA, and the stand by current is 4uA. Battery-powered application is available. Ultra-low power consumption, suitable for the battery-powered application. When the module is on the power-saving mode, the receiving response delay time of module can adjust the power consumption. Module can communicate with other modules which are work in different channels and addresses, it is easy for networking and repeater. For example: module A transmits AA BB CC to module B (address:
0x00 01, channel: 0x80), HEX format is 00 01 80 AA BB CC (00 01 refers to the address of module B, 80 refers to the channel of module B), then module B receives AA BB CC (only module B). Set communicate with other modules in same channel. It has the feature of FEC (Forward Error Correctionalgorithm,with high coding efficiency & good correction performance. In a sudden interference, it can correct the interfered data packets proactively, so that the reliability & transmission range are improved proactively. Without FEC, those data packets can only be dropped. The parameter will be saved after users set the parameters and it wont be lost if powered-off. After module powered-on again, the module will work as previous settings. 24 * 38.5mm, suitable for some application which has strict limitation for the size. All IO port lead out already for secondary development. If customers requirements, Ebyte accept customization of appropriate firmware. Ebyte has provided customized wireless modules to tens of well-known enterprises. Please contact us for more details. CC1310 has different size and packing, in which main difference is the number of GPIO. Ebyte has completely developed CC1310, including different size, frequency, power etc. the module address as 0xFFFF, existing UART module then the module can cannot meet the Page 3 of 11 Technical Support : support@cdebyte.com E70(915T30S)-User Manual-V1.0 Website: www.cdebyte.com/en 1.2.

For some MCU works at 5V DC, it may need to add 4 ~ 10K pull-up resistor for the TXD & AUX pins. 3.3 Reset No. 1 Description When the module is powered on, AUX outputs low level immediately, conducting hardware self-check and setting the operating mode on the basis of the user parameters. During the process, the AUX keeps low level. After this process, the AUX outputs high level and starts to work as per the operation mode combined by M2, M1, M0. Therefore, the user needs to wait the AUX rising edge as the starting point of modules normal work. 3.4 AUX description It can indicate whether there are data that has been sent through wireless, or whether all wireless data have been sent through UART, or whether the module is still in the process of self-check initialization. Indication of UART output It can be used to wake up external MCUIn continuous mode, the AUX indication isn't delayed.

Under subpackage transmission mode, the internal buffer size depends on the subpackage size, if the data packet length is 1024 bytes, the corresponding buffer is 1024 bytes, when the AUX=1, user could transmit data continuously no more than 1024 bytes . 2. Under continuous transmission mode, AUX=1, there is no limitation on user data input length. 3. Under WOR transmission mode, AUX=1, user could continuously input less than 84 bytes. 4. AUX=1 means the serial port data has been transmitted completely. 2 3 Configuration procedure of moduleonly when resetting and exiting sleep mode 4.
