LEMOS Announces LEMOS-LMX-WiFi Module

LEMOS (Barrington, RI) has announced the LEMOS-LMX-WiFi module, based on a Microchip PIC32MX695F512H 32-bit microcontroller coupled with a Microchip MRF24WB0MA WiFi radio. The PIC32MX695F512H contains 512K of program flash, and it is equally capable on the SRAM front incorporating 128K of readily available memory space. When used in a web-based embedded application, the LMX WiFi Module can support a full-function Microchip TCP/IP stack.

The I/O pins are capable of being multiplexed; select I/O pins have been terminated at headers to support I2C, SPI, and UART portals. In addition, the LMX WiFi exposes analog-to-digital converter pins. A number of additional PIC32MX695F512H general purpose I/O pins are also made available.

The part count for the LMX WiFi is kept at a minimum by employing the services of the PIC32MX695F512H’s internal processor clock. An on-board LDO voltage regulator allows an external supply that lies between +3.7 VDC and +5.0 VDC to power the LMX WiFi Module. The PIC32MX695F512H’s versatile I/O layout allows the LMX WiFi Module to be programmed to perform many functions that are hard coded into other WiFi modules. The LMX WiFi Module can be programmed to act as a Serial-to-WiFi device, a remote sensor platform, and a remote control device. The sensor and control applications are extendable to the internet; if an external device can use one of the LMX WiFi Module’s SPI or I2C portals, that device has the capability to go worldwide via the net.

For debugging and programming purposes, the LMX WiFi Module lays out a PICkit 3-compatible set of header pads, which includes the RST, 3V3, GND, IOD, and IOC header positions. This arrangement allows easy access to the programming and debugging resources offered by MPLAB X and the PICkit 3.

Features include:

  • On-board 500 mA 3.3-V linear regulator.
  • On-board user-accessible LED.
  • 16 GPIO pins.
  • GPIO pins support SPI, I2C, UART, A2D.
  • Programs with Microchip PICkit 3.
  • Firmware development supported by Microchip.
  • MPLAB X, XC32 compiler and Microchip application libraries.
