Plug-in sockets for Nano SocketLAN, Nano Socket iWiFi, and Mini Socket iWiFi as well as a socket for an I2C EEPROM.
The Connect One™ modules use 3V3 and are not 5V tolerant. For 5V systems, there is an onboard 3V3 regulator. Users must install a wire jumper to select 5V or 3V3 operation. There are level conversion circuits on RX, TX & RESET only. If used, the EEPROM needs to be 3V3-5V capable (Microchip 24xx00-24xx102x). All connections for both modules and system are exposed so users may route them, as desired. However, without level conversion, the SPI, USB & RMII lines can only be used with 3V3 system boards.
The Connect One modules are among the easiest Ethernet-to-Serial modules to use as there is no low level programming needed, you merely send AT commands similar to those sent to modems. Here is an example created in PicBasic Pro. The code burden on the embedded µC can be reduced by storing AT commands (in sequence) in an EEPROM and transferring them when a task is executed. A preliminary example illustrates this concept.
The Connect One wireless modules can use Ad Hoc or Infrastructure mode and they include SMTP/POP3 and SNTP protocols.
