Lonely Binary 3-Pack ESP32 WROOM-32UE IPEX Antenna GPIO LED for Arduino | 3 boards + antennas + PinPulse shields; WROOM-32UE, external 2.4GHz, extended range; dual M /F headers; MicroPython, ESP-IDF

Features

• 3-PACK ESP32-WROOM-32UE GOLD EDITIONThree ESP32-WROOM-32UE boards, each with dual-core 240MHz Xtensa LX6 CPU, 4MB flash, WiFi 802.11 b/g/n, and Bluetooth 4.2 (Classic + BLE). Lead-free ENIG (Electroless Nickel Immersion Gold) finish for good oxidation resistance. Ideal for classroom kits, multi-node IoT, and parallel projects.
• 3x PINPULSE SHIELDS WITH DUAL HEADER PINSEvery GPIO breaks out to both 2.54mm male and female headers, accepting any jumper wire (M-M, M-F, F-F) directly clean, fast prototyping with Dupont wires, breadboards, and sensors across all three boards.
• 3x EXTERNAL IPEX ANTENNAS FOR EXTENDED RANGEEach board has an onboard IPEX/U.FL connector paired with an included 2.4GHz external antenna for WiFi and Bluetooth signal coverage. Designed for IoT devices in metal enclosures, behind walls, or far from the router.
• VISUAL GPIO LEDS FOR REAL-TIME DEBUGGINGEach GPIO has a dedicated indicator LED driven through buffered high-impedance logic ICs (74HC14D buffers). See HIGH/LOW states instantly without a multimeter, while SPI, I2C, UART, and PWM signals stay clean.
• PLUG & PLAY DISPLAY CONNECTOR + CODE YOUR WAYDedicated FPC port connects to Lonely Binary displays (TFT LCDs, E-Ink panels, capacitive touch screens) via a single ribbon cable. Compatible with Arduino IDE, ESP-IDF, MicroPython, and C/C++. (Displays sold separately.)
