With the E1, OKdo has introduced a new developer board that is as small as it is affordable. Based on the NXP LPC55S69JBD100 microcontroller, the board has a host of other features, making it ideal for industrial IoT or automation projects.

The OKdo E1 is a particularly compact developer board. Retailing for £13.42 including VAT, the E1 is based on an NXP LPC55S69JBD100 microcontroller that integrates a dual-core ARM Cortex-M33 processor. The board supports up to 64 GPIO pins and has 320 KB of SRAM. Additionally, it features the following:

  • In-built CMSIS-DAP v1.0.7 debugger based on LPC11U35
  • Internal PLL support up to 100MHz operation, 16MHz can be mounted for full 150MHz operation.
  • SRAM 320kB
  • 32kHz crystal for real-time clock
  • 4 user switches
  • 3-colour LED
  • User USB connector
  • 2-off 16-way expansion connectors
  • UART over USB virtual COM port

The board supports USART, SPI, I2C and I2S, too. Moreover, there are two USB 2.0 controllers and an SD/MMC and SDIO card interface.

OKdo has provided extensive documentation on the E1, which it lasted on the unit's product page. The E1 is available to order now.
