Lonely Binary ESP32-S3 N16R8 Gold Edition Kit with PinPulse Shield

TheLonely Binary ESP32-S3 N16R8 Gold Edition PinPulse Kitpairs the ESP32-S3 N16R8 board with the PinPulse Shield. The board has alead-free ENIG (Electroless Nickel Immersion Gold) finishfor good durability, oxidation resistance, and signal integrity.

ESP32-S3 with AI Acceleration

Powered by theESP32-S3-WROOM-1module with dual-core 240MHz Xtensa LX7 CPU andAI vector instructions for on-device machine learning and neural network acceleration:

• 16MB Flash holds large programs, web servers, OTA partitions, and asset libraries
• 8MB PSRAM enables graphics-intensive applications: LVGL touch UIs, ESP32-CAM streaming, audio playback with decoding, AI/ML inference, and complex IoT systems
• WiFi 802.11 b/g/n+Bluetooth 5.0 LE(Low Energy only the ESP32-S3 does not support Bluetooth Classic)
• Dual USB-C ports one for native USB OTG (HID, MSC, CDC) and one for UART programming/debugging

PinPulse Shield

• Dual male & female 2.54mm headerson every GPIO accept any jumper wire type (M-M, M-F, F-F)
• GPIO indicator LEDsvia 74HC14D high-impedance buffered logic ICs see HIGH/LOW states without a multimeter
• Non-intrusive design LEDs do not load the bus, so SPI, I2C, UART, and PWM signals stay clean
• 15-pin FPC Display Connector connects to Lonely Binary TFT, E-Ink, and touch displays via a single ribbon cable (display sold separately)
