IR distance click
|
IR distance click carries Sharp’s GP2Y0A60SZ0F distance measuring sensor, which comprises of an integrated PSD (position sensitive detector), an infrared LED and a signal processing circuit. The measuring range is between 10 and 150 cm. The click is designed to run on either 3.3V or 5V power supply. It communicates with the target MCU over RST and AN pin on the mikroBUS™ line. |
Weather click
|
Weather click carries BME280 integrated environmental unit from Bosch. It’s a sensor that detects humidity, pressure, and temperature, specifically designed for low current consumption and long-term stability. The click is designed to work on a 3.3V power supply. It communicates with the target microcontroller over SPI or I2C interface. |
UV click
|
Design devices that warn you of excesive ultraviolet radiation levels with UV click. This click boards carries the ML8511 IC that is sensitive to UV-A (365-315 nm) and UV-B (315-280 nm) rays. |
Air quality click
|
Air quality click carries an MQ-135 sensor for detecting poisonous gases that impact air quality in homes and offices. The click is designed to run on a 5V power supply. It communicates with the target microcontroller over the AN pin on the mikroBUS™ line. |
Relay 2 click
|
Relay 2 click is a dual relay click board™, equipped with two single-pole solid state relays (SSR), built with the patented OptoMOS® technology. These SSR devices allow reasonably high current, up to 2A and voltage up to 30V (peak-to-peak). These relays also allow very fast switching time, thanks to the absence of any moving parts inside of them. Compared to a mechanical relays, solid state relays offer a whole range of advantages, such as very high reliability, arc-free operation with no snubbing circuits required, great input/output galvanic isolation, no EM/RF interferences, low driving power needed, resistance to wear over time since they do not use any mechanical parts, and much more compact sizes, compared with the traditional mechanical relays. |
4x4 Key click
|
4x4 Key click carries a 16 button keypad. The design of the board — inputs are read by a pair of connected 8-bit parallel-in serial-out shift registers — allows for multiple key presses at the same time. |
ROTARY R click
|
Rotary click carries a 15-pulse incremental rotary encoder with detents, surrounded by a ring of 16 red LEDs. It’s a perfect solution for adding a precision input knob to your design. |
GSM Click
|
GSM click is a compact and powerful GSM cellular network communication solution, featuring the GSM/GPRS Telit GL865-QUAD module. This module features a full set of options for the cellular networking and communication, such as the network status indication, jamming detection, embedded TCP/IP stack, including TCP, IP, UDP, SMTP, ICMP and FTP protocols, full GPRS class 10 implementation; GSM supplementary functions such as the call barring, waiting, forwarding, and holding, calling line identification presentation or restriction (CLIP/CLIR), integrated voice communication codecs, and more. This module also features an embedded Python Script interpreter, allowing users to run scripts from inside the module. |
