Battery-Powered Wireless PCB Design

I need a straightforward yet reliable custom PCB that handles wireless communication while running from a battery in the 5 V – 12 V range. The goal is to move quickly from concept to a manufacturable board without unnecessary extras.

Scope
• Translate my rough block diagram into a clean schematic focused on the RF or BLE/LoRa/Wi-Fi section (whichever suits low-power battery use).
• Lay out a compact double-layer PCB optimized for short antenna traces and solid ground planes to minimize noise.
• Provide Gerber files, drill files, and a basic BOM with readily available components so I can order prototypes immediately.

Key requirements
• Must be powered solely by a battery—no USB or AC input paths.
• Voltage regulation on-board for 5 V – 12 V input, with reverse-polarity and over-discharge protection.
• Clear test points for firmware flashing and signal verification.

Deliverables
1. Schematic (PDF + source in KiCad, Eagle, or Altium)
2. PCB layout file and manufacturing outputs (Gerber, drill, pick-and-place)
3. BOM with supplier part numbers

Please base the design on proven low-power wireless chipsets to keep the bill of materials lean. If you have previous battery-powered RF boards in your portfolio, that’s a plus—share a brief example so I can gauge fit.
