OKdo E1 Arm Development Board Launched with NXP LPC55S69 Cortex-M33 MCU

OKdo E1

We’ve just written about the launch of NXP LPC551x/S1x Arm Cortex-M33 MCU family, but OKdo has very recently announced a development board based on the previous generation LPC5500 Cortex-M33 processor, namely OKdo E1 powered by an NXP LPC55S59 dual-core Cortex-M33 processor.

OKdo E1 specification:

  • MCU – NXP LPC55S69JBD100 dual-core Arm Cortex-M33 @ up to 150 MHz with 640KB flash, 320 KB SRAM, FPU, Arm TrustZone, CASPER Crypto co-processor, and PowerQuad Hardware Accelerator for fixed and floating-point DSP functions
  • Expansion – 32x through holes and castellated holes with
    • Up to 9x Flexcomm interfaces (SW selectable as USART, SPI, I2C, or I2S interface)
    • GPIOs, I2C, ADC, UART, SPI, etc…
  • USB – 1x Micro USB 2.0 “User” port, 1x Micro USB 2.0 port for debug and power
  • Debugging
    • In-built CMSIS-DAP v1.0.7 debugger based on LPC11U35
    • Micro USB port with  UART over USB virtual COM port
  • Clocks – Internal PLL support up to 100MHz operation, 16MHz can be mounted for full 150MHz operation.
  • Misc – 4x push-buttons, 3x user LEDs (R, G, B)

The board is supported by NXP’s MCUXpresso IDE and is said to support other IDEs, as well as a range of middleware and open-source operating systems, but no details were provided.

OKdo has apparently developed a passive companion PCB that allows users to leverage Arduino shields and provide Digilient Pmod connector, but we were unable to find any precise information at the time of writing.

The E1 board is suitable for Industrial IoT, building control and automation, consumer electronics, general embedded, and secure applications.

OKdo E1 can be purchased for $14.49 on the company’s online store , where you’ll also find documentation such as schematics and the MCU datasheet.

I dont uderstand this mini boards, it just expose few pins of a huge IC. It is more interesting if it can bring more pins.
