SPI RF Wireless Module 

E01C - 2G4M11S: Ci24R1 Chip - Based SPI SMD Wireless Module

Chip Solution: Ci24R1
Communication Interface: SPI
Carrier Frequency: 2.4 - 2.525 GHz
Transmission Power: 11 dBm
Reference Distance: 120 m
Product Dimensions: 19 * 12 mm

Product Introduction: The E01C - 2G4M11S is a small - sized 2.4 GHz SMD wireless module independently developed by Ebyte with the Ci24R1 chip . It comes with a built - in PCB antenna and uses an industrial - grade high - precision 16 MHz crystal oscillator. Since the E01C - 2G4M11S wireless module is a pure RF transceiver module, it requires an MCU for driving or a dedicated SPI debugging tool.

Communication Features and Functions 

  1. With a maximum transmission power of 11 dBm, it can not only be powered by a battery but also greatly extend the wireless communication distance.

  2. Under ideal conditions, the communication distance can reach up to 120 m.

  3. It supports the globally license - free ISM 2.4 GHz frequency band.

  4. It supports air rates of 2 Mbps, 1 Mbps, and 250 kbps.

  5. It has 126 communication channels, meeting the application requirements for multi - point communication, grouping, frequency hopping, etc.

  6. It is connected to the MCU through a 2 - Pin hardware SPI interface, with a rate ranging from 0 to 10 Mbps.

  7. It is equipped with a professional RF shield, which provides anti - interference and anti - static protection.

  8. It is designed to industrial - grade standards and can be used for a long time in the temperature range of - 40 to + 85 °C.

  9. It comes with a built - in PCB onboard antenna, eliminating the need for an external antenna.
