nRF24L01+ Wireless & Screw Terminal IO Expansion Shield for Arduino Nano V3.0

nRF24L01+ Wireless & Screw Terminal IO Expansion Shield for Arduino Nano V3.0 is a multi-purpose carrier and breakout board engineered for Arduino Nano V3.0 (ATmega328P) modules. Furthermore, it combines a dedicated 8-pin (2×4) socket for 2.4GHz nRF24L01+ RF transceivers with an onboard AMS1117-3.3V high-current regulator, a 5.5mm × 2.1mm DC barrel jack, 3-pin GVS (`GND/VCC/SIG`) sensor headers, and perimeter screw terminals. Consequently, it resolves the notorious 3.3V brownout issue of bare Arduino Nano boards when transmitting 2.4GHz nRF24L01+ packets while breaking out every pin for rugged field wiring.

Key Features:

• Dedicated 8-Pin nRF24L01+ Wireless Socket: Pre-routed 2×4 female header connects the nRF24L01+ SPI bus (`CE, CSN, SCK, MOSI, MISO, IRQ`) directly to the Nano without messy jumper wires.
• Independent 3.3V LDO Regulator + Filter Capacitors: Supplies clean, high-current 3.3V power directly to the nRF24L01+ radio socket so PA+LNA modules transmit reliably without voltage sag.
• Perimeter Screw Terminal Blocks + 3-Pin GVS Headers: Exposes every Arduino Nano digital and analog pin on both clamping screw terminals and 2.54mm 3-pin servo/sensor headers.
• Onboard 7V–12V DC Barrel Jack Input: Powers both the Nano carrier and external 5V servos/sensors from a standard wall adapter or 2S/3S battery pack.
• Dedicated I2C & UART Header Banks: Includes 4-pin `GND/VCC/SDA/SCL` and `GND/VCC/TX/RX` pin headers for OLED displays and Bluetooth/GPS modules.

Technical Specifications:

• Compatible Host Board: Arduino Nano V3.0 (ATmega328P / LGT8F328P, 30-Pin DIP Layout)
• Wireless Interface Socket: 8-Pin (2×4, 2.54mm Pitch) nRF24L01 / nRF24L01+ Female Header

• Onboard Voltage Regulators: 5.0V Linear Regulator + Dedicated AMS1117-3.3V Regulator (Up to 800mA for 3.3V RF Rail)
• Breakout Terminations: Screw Terminals + 3-Pin GVS Male Headers (`D0–D13`, `A0–A7`) + 4-Pin I2C & Serial Headers

Pinout and Wiring:

• Nano Orientation: Insert the Arduino Nano V3.0 into the center dual-15-pin socket with its USB port facing the outer edge next to the DC barrel jack (verify `VIN` and `D13` silkscreen alignment).
• nRF24L01+ Socket Mapping: Pre-wired to Nano SPI pins `D9 (CE), D10 (CSN), D11 (MOSI), D12 (MISO), D13 (SCK)` and regulated `3.3V / GND`.
• Screw Terminals & 3-Pin GVS Headers: Connect sensor signal, 5V, and GND leads directly to `A0–A7` and `D0–D8`.
• Engineering Precaution: When an nRF24L01+ transceiver is plugged into the 8-pin RF socket, digital pins `D9, D10, D11, D12, and D13` are occupied by the SPI radio bus and should not be used for unrelated servos or relays.
