E30(915T20S)-User Manual-V1.0 Website： www.cdebyte.com/enPage 2 of 8 Technical Support : support@cdebyte.com1. Introduction1.1 FeatureE30(915T20S) is a 100mW wireless transceiver module(UART), half-duplex& transparent transmission, which operates at 907~922.5MHz(default: 915MHz), TTL Level, compatible with the 3.3V and 5V IO port.The module has the function of data encryption & compression. The data of the module transmitted overthe air features randomness. And with the rigorous encryption & decryption, data interception becomespointless. The function of data compression can decrease the transmission time & probability of beinginterfered, while improving the reliability & transmission efficiency.No.UsageDescription1Ultra-lowpowerconsumptionIt supports WOR to reduce overall power consumption. In power-savingmode(Mode 2), it can regulate overall power consumption by setting receivingresponse delay; The maximum receiving response delay can be configured as2000ms， and the average current is about 30uA.2FixedtransmissionModule can communicate with other modules which work in different channelsand 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 ofmodule B, 80 refers to the channel of module B), then module B receives AA BBCC (only module B).3BroadcasttransmissionSet the module address as 0xFFFF, then the module can communicate with othermodules in same channel.4FECForward Error Correction, high coding efficiency & good correctionperformance.In the case of sudden interference, it can correct the interfered data packetsproactively, so that the reliability & transmission range are improvedcorrespondingly. Without FEC, those data packets can only be dropped.5Sleep modeWhen the module works in sleep mode (mode 3), transmitting & receiving is notavailable, while the configuration is available. The typical current is 5.0uA in thismode.6ApplicationWith better capability of penetration and diffraction than 2.4G, E30(915T20S) issuitable for the open environment with few obstacles.1.2 Electrical ParametersNo.Parameter itemParameter detailsDescription1Size17 * 30mm-2Weight2.3gAverage weight3Frequency Band907~922.5MHz Default: 915MHz, channel:164ProcessLead-free, SMTTo ensure the consistency and reliability5Connector11PIN-2.0mmSMD6Supply voltage2.1 ~ 5.5V DCNote: the voltage higher than 5.5V is forbidden

When module A works as the transmitter (transparent transmission), all the receiving module with thechannel 0x04 can receive the data, so as to realize the broadcast.2.4 Monitoring address1. For example, set the address of module A as 0xFF FF, and the channel as 0x04.2.When module A works as the receiver, all the receiving module with the channel 0x04 can receive the

During the process, the AUXkeeps low level. After the process completed, the AUX outputs high level and starts to work as perthe operating mode combined by M1 and M0. Therefore, the user needs to wait the AUX risingedge as the starting point of module’s normal work.3.4 AUX descriptionAUX Pin can be used as indication for wireless send & receive buffer and self-check. It can indicatewhether there are data that are yet to send via wireless way, or whether all wireless data has been sentthrough UART, or whether the module is still in the process of self-check initialization.No.Description1【Indication of UART output】can be used to wake up external MCU.
E30(915T20S)-User Manual-V1.0 Website： www.cdebyte.com/enPage 7 of 8 Technical Support : support@cdebyte.com2【Indication of wireless transmitting】Buffer (empty): the internal 512 bytes data in the buffer are written to the RFIC (Autosubpackage). When AUX=1, the user can input data less than 512 bytes continuously withoutoverflow.Buffer (not empty): when AUX=0, the internal 512 bytes data in the buffer have not been writtento the RFIC completely. If the user starts to transmit data at this circumstance, it may causeovertime when the module is waiting for the user data, or transmitting wireless subpackage.Notes: When AUX = 1, it does not mean that all the UART data of the module have beentransmitted already, perhaps the last packet of data is still in transmission.3【Configuration procedure of module】Only happened when power-on resetting or exiting sleep mode.No.Notes for AUX1For function 1 & function 2 mentioned above, the priority should be given to the one with lowlevel output, which means if it meets each of any low level output condition, AUX outputs lowlevel, if none of the low level condition is met, AUX outputs high level.2When AUX outputs low level, it means the module is busy & cannot conduct operating modechecking.Within 1ms since AUX outputs high level, the mode switch will be completed.3After switching to new operating mode, it won’t be work in the new mode immediately until AUXrising edge 2ms later.If AUX is on the high level, the operating mode switch can be effected immediately.4When the user switches to other operating modes from mode 3 (sleep mode) or it’s still in resetprocess, the module will reset user parameters, during which AUX outputs low level.
