broadcast Wi-Fi Development Board

broadcast is a ESP-12F based wireless system development board that I designed. It has following features:
  • Designed from scratch using KiCad, considering the shield-safe layout and cost-effective materials for power and USB solution.
  • USB-to-Serial solution (CH340G) is a cost-effective product, which does not require additional drivers for Linux and Windows systems.
  • No bootloader required for initial flash, USB interface can be used even for initial flashing.
  • Possible applications involve Internet of Things and Cloud.
  • Features Espressif's one of the latest wireless modules, ESP-12F, which features revised antenna for better reception.
  • ESP-12F features following:
    • 802.11 b/g/n
    • Integrated low power 32-bit MCU
    • Integrated 10-bit ADC
    • Integrated TCP/IP protocol stack
    • Integrated TR switch, balun, LNA, power amplifier and matching network
    • Integrated PLL, regulators, and power management units
    • Supports antenna diversity
    • Wi-Fi 2.4 GHz, support WPA/WPA2
    • Support STA/AP/STA+AP operation modes
    • Support Smart Link Function for both Android and iOS devices
    • SDIO 2.0, (H) SPI, UART, I2C, I2S, IRDA, PWM, GPIO
    • STBC, 1x1 MIMO, 2x1 MIMO
