Lonely Binary 3-Pack ESP32-S3 N16R8 PinPulse GPIO LED 16MB for Arduino IDE | 3 boards + 3 PinPulse shields; WROOM-1, 8MB PSRAM, 240MHz; WiFi + BT 5.0 LE; dual USB-C; per-GPIO LEDs, dual M /F headers

Features

• 3-PACK ESP32-S3 GOLD EDITIONThree ESP32-S3-WROOM-1 boards, each with dual-core 240MHz Xtensa LX7 CPU and AI vector instructions, WiFi 802.11 b/g/n, and Bluetooth 5.0 LE. Lead-free ENIG (Electroless Nickel Immersion Gold) finish for good durability and signal integrity.
• 3x PINPULSE SHIELDS WITH DUAL HEADERS + GPIO LEDsEvery GPIO breaks out to both 2.54mm male and female headers, accepting any jumper wire type (M-M, M-F, F-F). Each pin includes an indicator LED via 74HC14D high-impedance buffered logic ICs see HIGH/LOW states instantly without a multimeter, while SPI, I2C, UART, and PWM signals stay clean.
• 16MB FLASH + 8MB PSRAM PER BOARDEach board's 16MB Flash holds large programs, web servers, OTA partitions, and asset libraries. Dedicated 8MB PSRAM enables graphics-intensive applications: LVGL touch UIs, ESP32-CAM streaming, audio playback with decoding, AI/ML on-device inference, and complex IoT systems.
• PLUG & PLAY DISPLAY + DUAL USB-CEach shield has a dedicated 15-pin FPC connector for Lonely Binary TFT, E-Ink, and touch displays via a single ribbon cable. Each board features two USB-C ports: one for native USB OTG (HID/MSC/CDC) and one for UART programming/debugging. (Displays sold separately.)
• CODE YOUR WAY + WHAT'S INCLUDEDCompatible with Arduino IDE, ESP-IDF, MicroPython, C/C++, and PlatformIO. Box includes 3x ESP32-S3 Gold Edition boards, 3x PinPulse Shields, and 1x USB-A to USB-C cable. Displays sold separately. Suitable for multi-node IoT, classroom sets, robotics, AI/ML on edge, and educators teaching embedded systems.
