ReRAM Click features ReRAM (Resistive Random Access Memory) module which contains the cell array made of 524.288 words x 8 bits, which totals 4 Mbits of data. The used memory module can withstand a large number of write cycles, it has data retention period greater than 10 years and it can read and write to random addresses with no delay. Besides these features that already mark this kind of memory modules a milestone in memory manufacturing technology, the device features block write protection, low power consumption and fast SPI interface that can theoretically work up to 5MHz. Because of its universal memory characteristics, ReRAM click can be used both as a non-volatile storage media, or temporary RAM expansion for storing variables in any embedded application.
ReRAM click is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.
SRAM click lets you add 1 Mbit of additional SRAM memory to your devices, via the 23LC1024 chip. It organizes the memory in 8-bit instruction registers and 32-byte pages.
Fan 2 click carries the MAX31760 precision fan-speed controller. It can measure temperature and adjust the fan speed to keep the temperature at the same level. Fan 2 click can also control two fans at the same time.
The click is designed to run on either 3.3V or 5V power supply. It communicates with the target microcontroller over I2C interface, with additional functionality provided by the following pins on the mikroBUS™ line: INT, AN, RST, CS.
Fan 3 click is the perfect choice for fan speed control and it can operate in seven discrete speed steps. Unlike the PWM regulation which can sometimes cause the infamous coil whining effect on some types of fans, this click board outputs the selected voltage via the MIC29152 voltage regulator from Microchip, driven through the MIC74 - a serial to parallel I/O expander and a fan controller from the same company, keeping it constant at the output. Fan 3 click works with 12V to 25V on its input connector and can be used whenever a noiseless solution with a variable fan speed is needed, for example - cooling of electronic components with the minimal possible noise produced.
