ODROID-W (Hardkernel) compatible with software for Raspberry-Pi


ODROID-W is a miniature computing module which is fully compatible with all software available for the Raspberry-Pi.

The W stands for: 
   - Wearable device development
   - Widely applicable Internet of Things (IoT) development
   - Workable DIY electronics prototyping

Processor Broadcom BCM2835 ARM11 700Mhz
Memory Samsung 4Gbit (512MB) LPDDR2 SDRAM
PMIC Ricoh RC5T619 includes DCDCs, LDOs, ADCs, RTC, Battery charger and Fuel gauge
DCDC TI TPS61259 is 5Volt step-up DCDC for USB host and HDMI block
Video Output HDMI type-D (Micro-HDMI)
USB High-speed USB 2.0 host
GPIO connectors RPi compatible 13x2-pin header on the top side as well as bottom side for 2-way stacking
20+6 pin header for additional GPIO/ADC/Power/USB connection
Total 32 GPIOs and 2 ADCs are available.
Camera connector 15pin MIPI-CSI2 (Pi Camera module compatible)
Memory card slot Micro-SD (T-Flash)
Power Micro-USB socket for 5Volt input
Li-Polymer battery connector (Molex 53398-0271)
RTC power Backup battery connector (Molex 53398-0271)
Dimensions 60 x 36 mm
Weight 8 gram


The ODROID-W measures a very small 60 x 36 x 7mm (2.4 x 1.4 x 0.3”). new features and improvements over the original Raspberry Pi:

- Li+ rechargeable battery charger and fuel gauge for portables, wearable and robots application
- Real Time Clock to keep accurate time without an Internet connection by just adding a coin battery
- 12-bit precision ADC to measure the dynamic voltage signals via two single-ended inputs 
- DC/DC step-down converters for higher power efficiency
- DC/DC step-up converter for 5Volt rails (USB host and HDMI) from a Li-Polymer battery
- USB Host port can be placed on top or bottom as preferred
- DIY friendly 0.1inch/2.54mm pitch IO connector (up to 32 GPIO ports) for handy prototyping

ODROID-W = RPI + RTC + ADC + UPS + Battery gauge with significant Minimalism
