Bridgetek strengthens portfolio of hardware supporting its microcontroller & display product lines
Building on the success of its CleO smart display offering and the array of accessories that accompany it, Bridgetek has now brought wireless connectivity into the mix. Transmitting and receiving in the 2.4 GHz frequency band, the CleO35-WiFi module is compliant with the commonly used IEEE 802.11b/g/n Wi-Fi standards. With the objective of enabling the control and monitoring of smart devices within the domestic environment, it can achieve +20dBm output power when in 802.11b mode. Support for WPA and WPA2 wireless security safeguards against unauthorized access to data streams. Drawing off a 3.3V supply, this module is supplied with a standard 16 pin 0.5mm pitch FFC cable that allows it to be connected directly to CleO35 board (with 3.5-inch TFT display) or to the CleO-IO shield so that it can be utilized by the larger CleO50 board (with 5-inch TFT display). Core to the module’s operation is an Ai-Thinker ESP-12S Wi-Fi subsystem. This is based on the compact, highly integrated 32-bit ESP8266 processor - with antenna switch, RF filters, power amplifier, low noise receive amplifier, digital peripheral interface and power management functions all included.
In addition, the company has introduced a new development module for its FT93x series of 32-bit performance-optimized microcontroller units. The compact (66.8 x 85mm), streamlined and simple to use MM930Lite module complements Bridgetek’s existing suite of development hardware and software tools. It provides engineers with a platform upon which they can evaluate the performance parameters of the MCU, carry out initial prototyping, or even construct sophisticated systems from the ground up within a short period of time.
Among the applications for which the MM930Lite is most suited are building security/door entry mechanisms, home automation infrastructure, industrial control implementations and embedded multimedia equipment. As well as its MCU, the module features 8MBytes of embedded Flash memory resource and a Micro SD card port for accommodating external memory. A broad range of interfaces are incorporated too. These include a Micro-B USB port for connecting to a USB host or delivering power to the module (as an alternative to the +5V DC supply connector), a 2.54mm pitch dual entry female header in a 2 x 8 pin arrangement, a 2 x 5 pin 1.27mm pitch female Micro-MaTch connector for software updating purposes, plus a 16 pin 0.5mm pitch FFC/FPC interconnect for SPI master interfacing (to support attachment to TFT display modules).
