I have just created another BLE MiniWear module called the MiniWear Simblee. It is an upgraded ble module that uses a IC that is half the size of the RFduino IC i was using, and has a lot of better features. This module is part of my Tiny Low Cost BLE Project so i apologise for double posting if you have already seen this.
Here is the Simblee being tested with the Blink Sketch
The Eagle design files have now been uploaded to Github
If you are interested, here are some Simblee specs copied from their website:
- Bluetooth® Smart
- Simblee interference immunity
- 3ms latency
- 10us accuracy (jitter)
- Physical range adjustable from a few inches to hundreds of feet
- Build iPhone and Android apps without Xcode or the Android SDK
- FCC, IC, CE, TELEC compliance approved
- Built in AES encryption engine
- 7mm x 10mm x 2.2mm
- 29 GPIOs (flexible pin configuration)
- <3uA ULP with clock running (run for years on a coin cell)
- 600nA ULP Sleep mode
- 8mA TX @ 0dBm
- 12mA TX @ +4dBm
- 10mA RX
- -93dBm receiver sensitivity
- -55dBm to +4dBm TX power
- ARM Cortex M0 processor
- Flash code space available for user application (no need for external controller)
- 6x ADC inputs, 4x PWM outputs, 2x SPI master/slave, 2x I2C, 1 x UART
- Temperature sensor
- Battery/Supply voltage monitoring
- Onchip UART bootloader
- OTA programming with hardware OTA disable
- Integrated 16 MHz crystal and 32KHz precision crystal
- Integrated antenna
- Integrated shield
In practice, i only breakout 3 of the simblee pins, as MiniWear is designed to work with the I2C communication protocol.
