Integration Notes & Hardware Guidance
- Power Supply - Use Type-C power for evaluation where possible, or provide a stable 5V / 3.3V pin supply with at least 500mA current capacity.
- 3.3V Domain - Treat module IO as 3.3V logic and add level shifting if external peripherals use another voltage domain.
- Firmware Download - Follow the board workflow: press the burn button and then press reset when entering firmware download mode.
- Antenna Clearance - Keep the onboard PCB antenna away from metal, shield cans, batteries, displays, and dense high-frequency circuits.
- Interface Planning - Confirm UART, GPIO, ADC, PWM, I2C, SPI, reset, boot, and RGB indicator usage before migrating from the kit to a custom design.
- Reserved Pins - Avoid using pins marked NC or shared with internal flash unless the final design has been reviewed against the official pin table.
- Power Noise - Add local decoupling and keep the power path low impedance to avoid brownout during Wi-Fi transmit bursts.
- Security Review - Plan secure startup, firmware signing, encryption, and debug access before moving from evaluation to production.
- RF Validation - Test range, packet stability, BLE behavior, and Wi-Fi throughput with the final enclosure and regional channel plan.
