Serial Workflow - Confirm UART port selection, reset timing, and download button behavior before firmware flashing or automated production tests. 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, and boot pin usage before migrating from the kit to a custom carrier board. Power Noise - Add local decoupling and keep the power path low impedance to avoid brownout during Wi-Fi transmit bursts. RF Validation - Test range, packet stability, BLE behavior, and Wi-Fi throughput with the final enclosure and regional channel plan. Thermal Review - Validate sustained Wi-Fi transmission under the target ambient temperature before final product release. Production Migration - Use the kit to verify firmware and peripherals, then map the same power, antenna, boot, reset, and IO requirements to the target hardware.
