SHAPE
Goblin head shaped PCB and 3D printed enclosure. Pointed ears, goblin face silkscreen, SMA antennas built into the ear tips. Fully custom — nothing off the shelf.

HARDWARE — v8 Dual Brain

• ESP32-C5 — Display brain. Drives the 3.5” ILI9488 touchscreen, handles WiFi scanning on both 2.4GHz AND 5GHz (the whole reason C5 was added)
• STM32WB55 — Radio brain. Runs all RF modules — CC1101 Sub-GHz, nRF24L01+ 2.4GHz, PN532 NFC, IR TX/RX, and onboard BLE 5.0
• Both chips talk to each other over UART at 115200 baud
• LiPo 3.7V 2000mAh battery with TP4056+Boost USB-C charging

WHAT IT CAN DO

• Scan and receive Sub-GHz signals (315/433/868/915MHz)
• Scan the full 2.4GHz spectrum across 126 channels
• Scan 5GHz WiFi networks (unique to v8)
• Read NFC/RFID tags — MIFARE, Ultralight, ISO14443A
• Capture and replay IR signals
• Scan for BLE devices
• Animated goblin mascot on every screen

FIRMWARE
Two separate Arduino C++ sketches — one per brain. Animated bo
