ESP32 LoRa V3 915 with 4x4 Membrane Keypad Compact development module that combines an ESP32 microcontroller board with a 915 MHz LoRa radio and an integrated 4x4 matrix membrane keypad. Designed for rapid prototyping and small production projects that need long range wireless communication plus local user input. Key benefits Long range wireless and local control in one module: LoRa 915 MHz radio enables low power, long distance data links while the onboard keypad makes direct control and configuration simple without extra hardware. Faster prototyping and fewer parts: combining the ESP32 and keypad reduces wiring and enclosure complexity, speeding development and deployment. Flexible integration: works with common ESP32 development environments and LoRa libraries, letting you reuse existing software and tools. What it does and how it helps Provides an ESP32based platform with LoRa 915 MHz transceiver for sending and receiving sensor data, commands, and configuration over long distances. Offers a 4x4 membrane matrix keypad for user input, menu navigation, PIN entry, or local commands, avoiding the need for additional input devices. Simplifies field setup and onsite adjustments by enabling local control and wireless telemetry from the same unit. Important attributes Function: ESP32 microcontroller plus LoRa 915 MHz radio and 4x4 matrix membrane keypad on a single module. Compatibility: compatible with standard ESP32 development environments and common LoRa libraries for quick software integration. Size and form factor: compact, low profile module suitable for enclosures, handheld devices, wallmounted panels, and compact sensor nodes. Keypad material and feel: low profile membrane keypad in a 4x4 matrix layout for straightforward numeric and command input. Performance: designed for low power operation typical of ESP32 and LoRabased systems, enabling battery powered and remote deployments. Practical applications Remote sensor node: collect environmental data from remote locations and transmit measurements over LoRa to a gateway. Use the keypad onsite to change sampling intervals or switch modes. Portable controller: build a handheld or wallmounted controller that sends commands to remote actuators or irrigation systems over LoRa, with the keypad used for direct input and quick configuration. Access or alarm panel: implement a simple access control or alarm interface where user PIN entry and local arming/disarming are handled by the keypad while events and status are reported via LoRa. What you can expect A single, integrated module combining ESP32 processing, LoRa 915 MHz wireless, and a 4x4 membrane keypad for compact, practical IoT and control solutions. Easy integration into existing ESP32 and LoRa projects using familiar development tools and libraries. A flexible building block for prototypes, field devices, and small deployments that require local input and long range wireless communication.
