## Description

The HardCode HC26060 puts an **NXP Kinetis E microcontroller** on a small, breadboard-friendly board — the same size and header layout as the popular "**Black Pill**". Choose the **KE02** (40 MHz) or the **KE04** (48 MHz) version.

Kinetis E chips are made for noisy, 5 V systems: they run from 2.7 V to 5.5 V. Power the module from USB-C (about 3 V on the MCU) or feed 5 V into the 3V3 pin and run the whole chip at 5 V.

A cheap Kinetis E breakout is hard to find. NXP's evaluation boards are Arduino-sized and often out of stock. The HC26060 gives you a real KE02 or KE04 on a breadboard, with all usable I/O on the headers.

##### Features
- **NXP Kinetis KE02 or KE04**, Arm Cortex-M0+, 64 KB flash
- **3.3 V or 5 V operation** (MCU range 2.7–5.5 V); I/O levels follow the supply
- **34 GPIO + RESET** on 2 × 1x20 headers, 2.54 mm, rows 0.6 in apart — fits a breadboard
- 12 ADC channels (12-bit), PWM timers, 3 UARTs, 2 SPI, I2C, 2 analog comparators
- **USB-C** 5 V power + **on-board USB-serial** on UART0 — serial console over one cable
- On-board 3.3 V regulator; diode-protected power paths (USB, 5V pin, 3V3 pin)
- **SWD header** (1x4 right-angle) for programming and debugging
- RESET + USER buttons, red user LED, green power LED
- No crystal needed (internal clock); crystal pins free on the header
- 20.78 × 52.81 mm (Black Pill V3.1 outline)

##### KE02 or KE04?
- **KE02** – 40 MHz, 64 KB flash, 4 KB RAM, 256 B EEPROM, 1× I2C. Pick it if you need the on-chip EEPROM.
- **KE04** – 48 MHz, 64 KB flash, 8 KB RAM, 2× I2C, pulse-width timer. Pick it for more RAM and the second I2C.

##### Programming
Program over SWD with a probe that supports Kinetis KE02/KE04 (for example SEGGER J-Link, CMSIS-DAP with pyOCD/OpenOCD, or NXP MCUXpresso). Choose the exact device: Kinetis E uses a different flash controller from other Kinetis parts. RESET for the probe is on header pin RST (not on the SWD header). Read the safety notes in the datasheet before your first flash (flash security byte, mass erase).

##### What's in the box
- HC26060 module (KE02 or KE04), assembled
- 2 × 1x20 pin headers + 1 × 1x4 right-angle SWD header — loose, to solder
- Quick-start card (QR → pinout + getting started)
- ESD bag

USB-C cable and SWD probe are not included.

##### Project Status
Rev A, first production batch, made in small numbers. Every unit is flashed with a test program and checked (power, LED, buttons, serial console) before it ships. SWD flashing tested by HardCode with a J-Link and a CMSIS-DAP probe, both through OpenOCD.
