A BT4.1 module maker based on Nordic nRF51 solution (nRF51822 & nRF51422)
After nRF51 Rev.3 IC currently has been widely applying for products and developments, Nordic has appealed the supplying time frame of Rev.1 & Rev.2 IC.
nRF51 Rev.1 & Rev.2 IC Last time order: 2015/12/31
nRF51 Rev.1 & Rev.2 IC Final Shipment: 2016/6/30
Customers are strongly recommended to switch to nRF51 Rev.3 IC in order to avoid the future firmware VS IC compatible concerns.
