Franzininho WIFI Developer Edition

(ENG)

Franzininho WiFi Developer Edition Board is a development board to evaluate ESP32-S2 Modules (Wroom and Wrover) and develop the new generation of Franzininho Boards. The Franzininho project was created to develop skills in people in the areas of electronics and programming, through activities in the DIY format and in conjunction with maker culture in Brazil.

As there are not many boards on the Brazilian market with ESP32-S2, we developed Franzininho WiFi to serve as the ESP32-S2 development platform and help us evaluate and validate applications with this SoC.

Features:

• ESP32-S2 Wrover:
  • Xtensa®single-core32-bit LX7 microprocessor, up to 240 MHz
  • 128 KB ROM
  • 320 KB SRAM
  • 16 KB SRAM in RTC
  • 2 MB (8 Mbit) PSRAM ( Only with Wrover Module)
  • WiFi 802.11 b/g/n
• Interfaces: GPIO, SPI, LCD, UART, I2C, I2S, Camera interface, IR, pulse counter, LED PWM, TWAI(compatible with ISO 11898-1), USB 1.1OTG, ADC, DAC, touch sensor, temperature sensor.
• USB Type-A Male
• RGB LED (WS2812) (GPIO 18)
• 40 pin broken out to 2x20 2.54mm header pins(36 GPIO) - Breadboard Friendly
• Reset and DFU (BOOT0) buttons to get into the ROM bootloader (which is a USB serial port so you don’t need a separate cable!)
• Serial debug pins ( TX and RX, for checking the hardware serial debug console) JTAG pads for advanced debugging access.
• 3.3 V Power On LED
• 3.3 V Regulator
• Power:
  • Micro USB port (default power supply)
  • 5V and GND header pins
  • 3V3 and GND header pins
• Dimensions: 72 mm x 30 mm
• Works with ESP-IDF or CircuitPython

License

The project is an open-source hardware and is available on CERN open hardware license.

The Franzininho WiFi board is certified in OSHWA: UID BR000006

A Franzininho WiFi é uma placa de desenvolvimento para avaliar os módulos ESP32-S2 (Wroom e Wrover) e desenvolver a nova geração de placas Franzininho. O projeto Franzininho foi criado para desenvolver habilidades em pessoas nas áreas de eletrônica e programação, por meio de atividades no formato DIY e em conjunto com a cultura maker, no Brasil.

Como não existem muitas placas no mercado brasileiro com ESP32-S2, desenvolvemos o Franzininho WiFi para servir como plataforma de desenvolvimento ESP32-S2 e nos ajudar a avaliar e validar aplicações com este SoC.
