The S100 Master - EZ-BLE PRoC Module is a Rhomb.io platform compatible module that allows wireless communications through Bluetooth Low Energy (BLE), one of the most used wireless technology standard widely spread on the consumer electronics industry and focused on the low power consumption. The device is BLE 4.1 compliant and includes an ARM Cortex M0 microcontroller with 128KB of flash memory. It can work as Master Module or as Slave Module. It also includes two voltage translators (FXMA108), which are used to reconfigure the signals that the EZ-PRoC receives.

There are available three variants of the Rhomb.io S100 Master - EZ-BLE PRoC Module. The next table highlights the main differences in between them.

Module specification

The Bluetooth Low Energy (BLE) is a wireless communication technology that works on the 2.4 GHz range and is focused on low power consumption. This technology is included on the most of the smartphones and tablets on the market, and is compatible with the Bluetooth former versions. The S100 Master - EZ-BLE PRoC Module is based on the Cypress System on Chip (SoC) EZ-PRoC. This is a programmable radio-on-chip fully certified and qualified for supporting BLE 4.1. It includes a 32-bit ARM Cortex-M0 microcontroller operating at 48MHz and with 128KB or 256KB of flash memory and 16KB or 32KB of SRAM, depending on the chosen module variation. The next table summarizes the mentioned features.

S100 Master - EZ-BLE PRoC Module features
Bluetooth 4.1/4.2 [1]
Microcontroller ARM Cortex M-0
Flash memory 128KB/256KB [1]
SRAM 16KB/32KB [1]

The S100 Master - EZ-BLE PRoC Module has been conceived for working as Master Module, but it could also work as a Slave Module. For doing so, the user should design a chip-to-chip protocol for maintaining the communication in between the master IC and the Bluetooth module. It also should be mentioned that, although some guidelines about the used SoC are explained on this document, it is quite recommended to consult for more specific information the Cypress official documentation (Cypress documentation).
