WiFi Modules

Compact WiFi module with ESP8285H16 that adds remote control and real-time monitoring to Sinilink programmable power supplies, mounts directly on the board via a dedicated connector, communicates via 3.3V UART with a ModBUS bridge for commands and telemetry, operates at 3.3-5V with internal regulation, and supports advanced integration through alternative firmware such as ESPHome or Tasmota.

Compact module for passive 802.11 sniffing, captures MAC addresses from probe requests for monitoring nearby WiFi devices without network association. Quickly transmits data over UART in hex format with timestamp and CRC, has a FIFO buffer to prevent losses, and an adjustable RSSI threshold for distance filtering. Compatible with 3.3V or 5V, ideal for pedestrian traffic analysis and presence detection.

Adds wireless control and monitoring for the RD6006 power supply, by connecting directly to the existing internal socket, without modifications. The module is exclusively compatible with the RD6006, uses the integrated ESP8266 for WiFi communication, allows quick access to settings and reading of parameters remotely, ideal for automation and integration into laboratory projects.

WiFi module based on ESP8266, ideal for quickly connecting Arduino and IoT projects to the 2.4GHz network, interfaces simply via serial UART at 115200 bps, runs on 32-bit architecture with 5V power supply and 3.3V logic, includes PCB antenna for compact installation and supports WEP, WPA, WPA2 security for reliable transmissions.

WiFi Shield to quickly add ESP8266 connectivity to Arduino boards, directly compatible with UNO R3, Mega 2560 and Leonardo, can also work independently as ESP-12E with all pins accessible. It has an integrated 3.3V level converter, 4 DIP switches for selecting the working mode, programming via USB or OTA and support for AP and Station.

Compact WiFi module to quickly add 802.11 bgn connectivity to microcontroller projects, works standalone with 2 GPIO or as an extension for Arduino via the RX TX serial interface. Offers AP, STA or AP+STA modes, includes integrated TCP IP stack, runs at 3.3V and has 1MB flash memory for IoT applications.

Compact WiFi module for IoT projects, based on the original ESP12-E AI , offers 2.4GHz 802.11 bgn connectivity and integrated TCP IP stack for fast network communication. Includes low-power 32-bit MCU and 10-bit ADC for signal control and acquisition, supports STA AP and STA+AP modes with WPA WPA2 security. Operates at 3.3V.

Compact solution for WiFi automation and remote control of consumers, combines a 5V relay with the ESP8266 ESP-01 module mounted directly in the socket. Includes 5V-3.3V step-down for powering the ESP, relay controlled from GPIO0 with LOW activation, support for Station and Access Point modes and UART communication for configuration and programming.
