3-Pack WROOM-32UE IPEX Antenna GPIO LED for Arduino 【3-PACK ESP32-WROOM-32UE GOLD EDITION】Three ESP32-WROOM-32UE boards, each with dual-core 240MHz Xtensa LX6 CPU, 4MB flash, WiFi b/g/n, and Bluetooth (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 PINS】Every GPIO breaks out to both 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 RANGE】Each board has an onboard IPEX/ connector paired with an included 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 DEBUGGING】Each 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 WAY】Dedicated FPC port connects to 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.) From Zeros to Heroes One Bit at a Time: empowers makers with affordable modules, Tinkerblock kits, and sensors for IoT/STEM.  |
